21 is certainly a big birthday, so you've gotta do it up right!
And Selena Gomez has certainly done that as she's been celebrating all week.
The party train rolled on this weekend as Selenita stepped out last night with her girlfriends - yup, no Justin Bieber - for dinner at Boa in El Lay. But that wasn't all because the group then headed to Bootsy Bellows where they likely got their groove on!
It's rumored they had a table, spent the night dancing, and didn't leave until closing time. Now that is a 21 year old right there!
But the crazy thing is that this isn't even her BIG birthday celebration because she's supposedly going back out tonight for a gypsy-themed party!
Damn, girl, even most 21-year-olds can't keep up with all that!
