Tim Howard -- HOT CLUB, HOT CHICKS

Now that he's a bona fide rockstar, Team USA goalie Tim Howard hit the Hollywood club scene Saturday night ... and left with a couple of smokin' hot chicks!

Howard and a buddy hit up 1Oak on the Sunset Strip -- and left in a taxi with 2 very attractive ladies.

Howard is reportedly dating former U.K. "Big Brother" star Sara Mclean -- and the smaller brunette woman he was with sorta looks like her ... but it's hard to tell for sure.

Also, according to Mclean's Twitter page -- she was at a cricket match in London on Saturday.

So ... is it Mclean? Has Howard moved on? Are the chicks he left with just "good friends?"

Either way, sweet v-neck bro.
