Time's Most Influential People Gala

Hollywood power couple Ashton Kutcher and Demi Moore attended Time magazine's "100 Most Influential People in the World" gala at Lincoln Center's Frederick P. Rose Hall in NYC. The celebrity Twitter king and creator of "Punk'd" was one of the honorees.

A sparkling Taylor Swift mingled with President Bill Clinton at the soiree. Both scored spots on Time's list of men and women "whose power, talent or moral example is transforming the world."

Mariah Carey's hubby (three times over) Nick Cannon walked the red carpet solo.

Jennifer Lopez made jaws drop in her stunning, strapless Zuhair Murad Haute Couture ball gown, Judith Leiber clutch, and Sergio Rossi slingbacks.

Katy Perry lit up the arrivals line in a Lorraine Schwartz statement necklace and a floor-length CuteCircuit dress, which glowed thanks to concealed strands of lights stitched into the seams.

Oscar de la Renta escorted Oprah Winfrey down the red carpet, who happened to be wearing a gorgeous navy gown custom made by Mr. de la Renta himself!

Swifty has a new boyfriend (YES!)

The country cutie is “still having a love affair with notorious ladies’ man John Mayer,” claims Star.“Still”? Um, Swift was never in a relationship with Mayer. But let’s see what the tab has to say.According to a so-called “source,” Swift has been “meeting up all over the country” with Mayer, behind the back of her alleged boyfriend Cory Monteith. “Taylor will drop anything to see [Mayer],” reports the magazine. All he has to do is text her, another “source” claims, and she’ll “come running” “no matter what time it is!”So let’s get this straight.Two superstars with fully booked schedules — and whose every move is followed by a voracious press — have been meeting secretly from coast to coast at the drop of a hat?Forgive us for thinking the whole thing is absurd.But just in case, we reached out to sources close to Swift, all of whom tell Gossip Cop the story is complete nonsense.
