Celebs were all over L.A. yesterday for two big fashion events.  TopShop/TopMan officially opened in the west coast city, and celebs flocked to the store's party to celebrate.  Plus, a big Tommy Hilfiger L.A. Flagship store opening party went down.

Pics inside...

Fresh off some drama at JFK airport with TSA pushing them PAST security, Kim & Kanye bumped their way to the Topshop Topman LA Opening Party at Cecconi's West Hollywood last night.

Kimmy covered her growing baby bump with a feathery frock and leather pants.  And Kanye threw on a real shirt and his leather pants as well.

Fab chick Christina Milian looked great in a sequin crop top and peachy trousers with a sheen.  Loves this look.  Not sure what that fat diamond on that ring finger is all about though...

Chris Brown got into the V-Day spirit with a red heart over his chest.  He later met up with Rihanna to go party it up at their fave nightspot.  And is also caught up in legal drama as it was just reported that he and Drake are now suing EACH OTHER over that NYC Greenhouse nightclub brawl from a while back.  TMZ has the story.

Jennifer Lopez kept it futuristic with her look:

Lots going on here with this look...and we kinda like it.

Actress KeKe Palmer made her way to the event.  Not loving this dress though.

Solange & her 'fro made their way to the event in a longer dress than the night before at her sis' Premiere.

Lionel Richie and his "date" hit the event.

Oh hey LaToya.

"Idol" judge Randy Jackson kicked it with his co-star Ryan Seacrest.

And will.i.am was also in the mix.

Over at the Tommy Hilfiger LA. Flagship Store opening:

Swizz Beatz threw on his white blazer for the fresh occasion.

And his wife Alicia Keys was pretty in red:

Nice.  She knows what flatters her bod.

Olympian Allison Felix kept it chic in a blue suit and sheer paneled top as she posed with Mr. Hilfiger himself.

Estelle also rocked a cute looked while posing it up with the man of the hour.

I don't knw what Estelle has changed in her style department recently, but whatever--or whoever--it is....keep 'em.  Love this look.

"ET" correspondent Rocsi rocked a cute flirty dress for the event.

J.Lo pulled double fashion duty hitting up this event after the Topshop/Topman party.

Former "CSI" actor and Jumping The Broom star Gary Dourdan escaped all his legal problems for a bit to hit up the carpet.
