Barack Obama once again proved he's the most qualified candidate in the field ... TO SING ... 'cause El Presidente once again flexed his voice during an impromptu blues session with B.B. King -- and it was AWESOME!
It all went down at an event at the White House last night ... when Obama went to thank King and Mick Jagger for performing ... and Buddy Guy talked Obama into joining the gang on stage.
Then -- the guy who impressed with Al Green's "Let's Stay Together" -- began singing along to "Sweet Home Chicago" ... and KILLED IT.
And as the band played him off, Barack and Michelle made their exit ... like frickin' rockstars.
Rihanna collaborating with Chris Brown has the newsroom up in arms -- because everyone still remembers what he did to RiRi's face. Are we crazy? (That was rhetorical)
Aubrey O'Day's big mouth has landed her in hot water again ... only this time it's not because of what she said ... it's what she sang.
The "Celebrity Apprentice" contestant is being sued over a segment in the finale of her Oxygen reality show, "All About Aubrey" ... in which she sings on top of a track produced by her friend Adonis Shropshire.
Here's the rub -- according to the suit, Adonis created that particular beat for ANOTHER artist and didn't have the right to pass it on to Aubrey.
Now, the company that claims it owns the beat is suing Aubrey, Oxygen and Adonis ... alleging they all contributed to the alleged beat jackery.
The company is suing for unspecified damages -- and an order preventing Aubrey from performing the song ever again.
Rihanna and Chris Brown have reconciled ... at least professionally ... because the former couple have collaborated on 2 brand new songs.
It's only been 3 years since Brown pummeled Rihanna's face during a late night argument in L.A. ... but the singer and her ex-con ex-BF have each released songs featuring the other's voice. One is a remix of Rihanna's song, "Birthday Cake" and the other is a new version of Chris Brown's, "Turn Up the Music (below)."
Both songs hit the Internet this week ... and both Rihanna and Brown have been pushing the songs on Twitter.
The songs seem to prove the rumors ... that Rihanna has forgiven Brown and is willing to move on. Earlier this week, Brown tweeted Rihanna "Happy Birthday" ... and Rihanna actually responded, "Thanks."
Rihanna is currently in London (see photo above) ... and Chris Brown was most recently seen in Miami.
As we previously reported, Brown is currently in a relationship with a woman named Karrueche Tran ... and we're told the two seem very happy together.
Elton John had a crappy weekend ... a very crappy weekend ... because the Rocket Man came down with a nasty case of food poisoning ... TMZ has learned.
E.J. was supposed to perform at Caesars Palace in Vegas this past Friday and Saturday night ... but the singer had to back out when something he ate ... backfired.
Elton's rep tells us John is doing "much better now" ... and will be ready to go in time for his next concert later this week .... in Guadalajara, Mexico.
Dolly Parton is eating her words after calling "I Will Always Love You" HER song -- despite it being made famous by Whitney Houston -- and now tells TMZ, she's happy to share it with the late R&B legend.
Dolly took a lot of flack after her previous statement following Whitney's death -- "I will always be grateful and in awe of the wonderful performance she did on my song."
But Dolly's loosening her grip on her country classic -- telling us, "I did not know Whitney, nor any of her family personally; but she will always be a part of my heart and I will always be grateful for her awesome performance and success with our song “ (emphasis hers).
Dolly adds, "My heart is with Whitney and her family as they lay her to rest ... I Will Always Love You."
Dolly's original version of the song was released in 1974. Whitney famously covered the track in 1992 for "The Bodyguard."
Nick Carter has two more stops on his tour, but after that the singer plans on taking some time off to grieve following the death of his sister ... sources close to Carter tell TMZ.
According to our sources, Carter will play the last two tour dates (tonight in Chicago and tomorrow in Columbus) in memory of his sister Leslie, who passed away on January 31.
After that, we're told Nick will not schedule any more appearances ... and will take a couple of weeks to go off and deal with his sister's death. Our sources say Nick is still dealing with the fact that he missed her funeral.
As TMZ previously reported, the Carter family believes Leslie overdosed on prescription drugs.
Oksana Grigorieva performed live in Hollywood last night and while the place was packed, Oksana's performance was ... well you can listen for yourself.
Oksana played the Gardenia Lounge in West Hollywood last night as she tried to further the singing career that was once helmed by ex-boyfriend Mel Gibson. He was her executive producer at one point and when they split, securing the rights to her music was Oksana's mission.
As for the show, our guy inside said the place was quite crowded and everyone was there specifically to see Oksana.
It seems cray ... but a simple warning that Jay Z and Kanye West included at the top of their "N**gas in Paris" video may have been the difference between life and death for some of their seizure-prone fans ... this according to multiple epilepsy organizations.
The concern is obvious ... since the video is filled with strobe lights and quick edits. The warning at the top of the video reads, "This video has been identified by Epilepsy Action to potentially trigger seizures for people with photosensitive epilepsy. Viewer discretion is advised."
Now, the Citizens United for Researchin Epilepsy tell TMZ ... "50,000 individuals lose their lives each year due to seizures and related causes. We applaud artists like Kanye West and Jay Z who recognize the potential dangers in their videos, movies and performances and are conscientious enough to warn patients and their families about the risks."
And CURE isn't alone in their praise ... a rep for the Epilepsy Therapy Project tells us the organization "appreciates the sensitivities that Kanye and Jay Z showed in appropriately warning individuals with photosensitive epilepsy that their video may cause seizures."
The rep adds, "Given the 4 million people who suffer from epilepsy in the US alone, we need to work together with the music industry on how best to destigmatize the condition and stop seizures and epilepsy once and for all so everyone can enjoy the music."
Fred Durst partied like it was 1999 Monday night -- reprising the classic Limp Bizkit song "Nookie" at an L.A. bar ... and it was all caught on tape!
Sources tell TMZ, Durst hit up open karaoke night at Rock & Reilly's with Nick Swardson and Cedric Yarbrough from "Reno 911" -- and the trio performed a bunch of other songs ... like Gnarls Barkley's "Crazy."
Overall, the beatboxed version of "Nookie" ain't too bad -- in fact, we now feel slightly less embarrassed about listening to Limp Bizkit in high school.
Jigga what? Liza Minnelli proved she has mad props for rap mogul Jay-Z and checked out his concert at Carnegie Hall in NYC last night.
