Nick Cannon, Mel B., Ray J, Christina Milianand other NBC stars came out to promote their upcoming projects for the NBC Upfronts in California yesterday. See the celebs in their springtime best inside....

Doing his bestMorris Day& The Timeimpersonation,"America's Got Talent" host Nick Cannon donned THIS outfit for the 2013 NBC Universal Summer Press Day....and had his mirror and mirror guy on hand.  That damn Nick...

Easter brunch fresh.  Held at Langham Huntington Hotel& Spa in Pasadena, California, Mr. Cannon kicked off the event in his springtime swag complete with an attendant and a cane.

Nick's"AGT" judge Mel B. has already drawn some"boos" from the studio audienceduring tapings, but we'll give her applause for her red carpet look.

She added a little springtime"spice" to the event while rocking a body hugging black dress with a center panel of contouring with black and white stripes.  Nice.

Meanwhile, Cash Money recording artist Christina Milian looked like a doll...who couldn't stop playing in the concealer....as she promoted her gig on"The Voice."

She looked fab in a lace blue mini dress and nude heels.  Super cute look for her. No more ring though?  Maybe she didn't want to continue to lead her fans on with making them believe she and boyfriendJas Princeare engaged.

Before the red carpet, Christina got her nails and toes pampered, tweeting"Quick pedi w the crew.. Lol".

Ray J, who's hostingBad Girls All-Star Battle, walked the red carpet.  This guy...

The reigning Miss USA,Nana Meriwether, looked amazing as well.  Fab times all around.
