Demi Lovato Is All Smiles Leaving The Roosevelt

Demi Lovato had an awesome - and late! - night out with her BFFs.

The singer/actress was all smiles as she left The Roosevelt Hotel in Hollywood Wednesday night. Earlier, Demi and jewelry designer/model pal Hanna Beth checked out the Noon by Noor clothing line launch party at the Sunset Tower Hotel in West Hollywood.

And Demi was in total control of the evening, driving her Mercedes-Benz away herself. No helping hands needed!

The only frustrating part for the happy star ... having to shoo away photogs as she tried to maker her exit. Considering how well the "Skyscraper" singer has been doing since she got out of rehab, we'd say that's just a minor bump in the road ... literally.

Wonder if they were bonding over their mutual ex? After all, both Hanna and Demi dated Miley Cyrus' big bro Trace Cyrus! In any case, Demi, 18, definitely had a great night. At 3:30 a.m. she Tweeted:

"Such a funny night with my ladies @jOYCEBONELLi & @TheHannaBeth.. Way past my bedtime.." #insomnia

It's no wonder that Demi was in such good spirits. See what else she Tweeted ... after the jump.
