ET has the details...

Break out the party favors! BRITNEY SPEARS is set to host a bash on Feb. 16 at The Scandinavian Style Mansion, a private residence in Beverly Hills, People is reporting.

"Britney has said 'yes,' to hosting it," CLAUS HJELMBAK, the Danish businessman behind the event, tells the mag. "I am beyond excited because the experience she gave everyone in December was amazing. She absolutely made my event."

As ET previously reported, the "Toxic" singer celebrated her 26th birthday -- along with PARIS HILTON -- at the mansion last December.
