Tonight at 9 p.m. Piers Morgan welcomes Mehmet Oz for a unique and informative face to face interview, detailing everything from erectile dysfunction, to wine, and cholesterol.

Joining the "Piers Morgan Tonight" host in studio, television's "Dr. Oz" takes Morgan's blood pressure, and announces his findings:

"You're number is 134 over 82," the guest reveals.

While it's an average reading in America, Oz insists it's not optimal:

"What it translates to, is that your life expectancy is going to be several years shorter than if your number was the optimal number."

Well known for his appearances on "The Oprah Winfrey Show," Oz now has his own program, launched in 2009 by Harpo Productions.

Coming up this evening at 9 p.m., "Piers Morgan Tonight" welcomes singer-songwriter and record producer Cee Lo Green for an honest and revealing sit down.

Joining Piers Morgan for an exclusive face to face interview, the artist behind such hits as "Forget You" and "Crazy" opens up about losing his mother while still in his teens:

"It's definitely a rude - a very rude awakening. But I was able to see some - some purpose in it," Green tells the host. "I've also answered this question on occasion by saying that I had actually died and my mother lives on. You know, my work, my aspirations and my ability, my, even down to my articulation, is my mother's will, my mother's work and want for me."

When asked by Morgan if Green's late mother would be proud of his success, the vocal coach on NBC's "The Voice" switches to present tense:

"I think she still is," he declares. "I think she's definitely alive in - in all of this positive energy surrounding, you know, what's become of me."

Watch the above clip, and listen to the interview, then tune in tonight at 9 p.m. as Green explains his unique sense of style and showmanship, in advance of his upcoming summer in Las Vegas.

On Thursday, Piers Morgan used his "Only in America" segment to slide on his dancing shoes and pay tribute to Donna Summer.

As the singer passed away at the age of 63, Morgan concluded her legacy is undeniable:

"She was quite simply...the queen of disco," declared the host. "A young woman from Boston with an amazingly powerful voice, but more than that, the power to make people dance."

With a playlist that eclipsed nearly four decades, Summer's collection sent Morgan on a trip down musical memory lane:

"'Love to Love You, Baby,' 'I Feel Love,' 'Hot stuff,' 'On the Radio,' 'She Works Hard For the Money,' all classics in their own lifetime."

With the passing of singer Donna Summer on Thursday, "Piers Morgan Tonight" invited Aretha Franklin to share her thoughts and memories. Referring to the artist known as the "Queen of Disco," the "Queen of Soul" reflected on fellow music royalty:

"I thought she was a very gracious and a very nice person. Always beautifully gowned and well spoken," remembered Franklin in an exclusive interview. "We won't forget all those many hits she put out there."

Meanwhile, Thursday also revealed that a G.O.P. "Super PAC" is preparing for the release of an ad campaign more controversial and provocative than anything seen to this point. Designed to attack the president by resurrecting his relationship with Rev. Jeremiah A. Wright Jr., the plan is timed to coincide with September's Democratic Convention.

Following his candid and entertaining interview for "Piers Morgan Tonight" (airing tonight, 9 p.m.), singer-songwriter and record producer Cee Lo Green joined us for an exclusive sit down, in a location that's seemingly been named in his honor: the "Green Room."

Having just wrapped his second season as a vocal coach on NBC's "The Voice," Green reflected on using social media to interact with his fan base:

"You just try to apply poetry to your personal life," shared one half of the former soul duo "Gnarls Barkley." "I just take a poetic approach with the way that I communicate – with, not just women – but everyone."

As new evidence is released in the Trayvon Martin case, tonight Piers Morgan welcomes Mark O'Mara for his expert analysis and reaction.

Limited by legal guidelines, O'Mara is unable to speak about the discovery material specifically. However, he does share his thoughts on the process to this point:

"Well, we knew it was coming. It's several pieces of the puzzle that we now have to put together," says George Zimmerman's defense attorney. "I would only ask that everyone wait until we have the whole pieces – all of them together – to look and see what the whole picture is."

With more discovery to come, including a whole series of depositions, the "Piers Morgan Tonight" host asked about the possibility of the case never making it to trial: FULL POST

On the heels of recently released discovery materials in the Trayvon Martin case, this evening "Piers Morgan Tonight" invites attorney Benjamin Crump to share his insight and reaction.

As Thursday's autopsy reveals trace amounts of THC to have been found in Martin's system, Crump points instead to the tests that were not run:

"What's really relevant is the fact that there was no toxicology report on George Zimmerman," says the attorney for Trayvon Martin's family. "We don't know what else was in his system, with the prescribed medication that he was on, to have him get out of his car in the rain, and profile, pursue, and confront Trayvon Martin and then kill Trayvon Martin."

Asked about a new photo showing Zimmerman with an injury to his nose, Crump suggests it pales in comparison to what his client's son endured: FULL POST

On Wednesday, Piers Morgan used his "Only in America" segment to surface in support of a bottomless fried fish special:

"Meet Bill Wisth. He really loves the all-you-can-eat fish fry at a local restaurant called Chuck's Place."

Tipping that scales at 350 pounds, Wisth paints an imposing figure at 6 feet 6 inches tall. But after getting his hooks into 12 servings of cod, the Wisconsin restaurant cut his line.

"Considering his carriage, that's like a a side salad," said Morgan of Wisth's delicious dozen. "It's simply not enough."

So the fish fan refused to take the bait. He called the cops, furious about his undersized serving.

On Wednesday night, "Piers Morgan Tonight" welcomed actor and screenwriter Billy Bob Thornton for a candid and genuine interview.

During his interview with Piers Morgan, Thornton talked about how social media and the system are taking over:

“The system has always found a way to control people, and I think this time they’ve done it by selling them things that make them feel accepted, loved, and important. Everyone should feel that but I think they should feel it through natural things.”

Thornton went on to draw the contrast between how people used to interact and how the system is making it difficult to continue doing things the same way – something he talks about in his book "The Billy Bob Tapes: A Cave Full of Ghosts."

"When it becomes a tool for people's hatred and jealousy – we're losing the magic in life because people aren't communicating and they're not going through the process of life," Thornton said.
