After announcing their engagement yesterday, Britney Spears and Jason Trawick were in the mood for a sweet celebration, so they headed to Las Vegas and partied the night away at the Sugar Factory American Brasserie and Chateau Nightclub & Gardens.
Of course, they were also celebrating Jason's 40th birthday, and sources at the bash tell us the pop princess couldn't have been happier. The lovebirds cozied up in a secluded corner of Sugar Factory's Chocolate Lounge, and apparently Britney couldn't keep her eyes off of her brand new engagement ring, as she "put her hand out in front of her and gave Jason kisses throughout the meal."
And let's not forget about dessert! Britney and Jason noshed on cupcakes, gumdrops and other sweet treats, and she even surprised her beau with a two-tier black and white birthday red velvet cake, which is his favorite. Awww!
