It was a hot pink night for YBF chicks Rihanna and Tyra Banks.  Both of the ladies showed up to Tuesday night's TIME 100 Gala celebrating its '100 Most Influential People In The World.'  And since the two fabulous ladies made the list, they made a statement in pink on the red carpet.

At Frederick P. Rose Hall, Home of Jazz at Lincoln Center in New York City, Rihanna showed up in a strapless hot pink taffeta Marchesa gown with a slight origami & gathered plunged neckline and a hi-low hem.  The now black-haired singer looked fresh & pretty, pulling off the 80's prom look with a surprisingly refreshing appeal. 

And the chick didn't let a pretty party dress keep her from partying her way.  She tweeted:

Well....2nt consisted of us singing Bob Marley, drinkin Vintage Scotch, and my mom thinkin a joke abt [Ashton] Kutcher was appropriate! #Thxtime100

Ri, who hit the red carpet and performed at the event, gushed on the red carpet about how special this honor is saying, "I can't believe I'm sitting in one of those slots--100 slots. There's so many people in the world. It feels special. It really is surreal."

With big diamond earrings and her black Louboutin pumps, the "Cake" singer was spotted leaving her hotel--Gansevoort Park Ave--before the event:

We're feelin' the look as she paired her Resort 2012 gown with Christian Louboutin ‘Bois Dore’ crystallized heels.  And clearly so is Ri herself as she tweeted pics in her gown:

And a pic with her mom who flew to NY to surprise her for her big honor. 

The "We Found Love" singer performed while rocking a jacquard strapless blouse & metallic pants both from the Stella McCartney Autumn 2012 collection:

And headed back to her hotel to wrap the night. 

Also honored at Tuesday night's event was mogul & Harvard Business School grad Tyra Banks:

In an equally eye catching hot pink color, Tyra rocked an elegant pink strapless gown for her big night:

She's not letting the big day of firing day at her show, "ANTM" (The Jays and Nigel Barker all got fired) affect her "pretty"...even though this makeup is a bit strong. Still fabulous nonetheless.
