Britney's House Party For Her Bday > Your Party @ Ya Cousin's Apartment's Clubhouse

Sounds like Britney Spears had herself a very happy birthday indeed!

The singer, who turned 28 yesterday, received a shiny new white BMW convertible with a ribbon on it and balloons inside during a party at her Calabasas home.

Birthday girl Brit was in good spirits, a source tell E! News. She was dressed sexily, in a blue velvet blazer, shorts and fishnet stockings.

She had a cake presented to her around 10 p.m., but there was no champagne toast, since no alcohol was served at the soiree, the insider tells us.

"It was really mellow," says the source.

So who was on hand to help her celebrate?

BF Jason Trawick (who went shopping with her earlier), dad Jamie, her two boys, manager Larry Rudolph, as well as some backup dancers and friends.

If you didn't get an invite, don't feel bad. Less than 20 people attended.

No word on where her mom and sister were.
