Boxing champ Floyd Mayweather, who is serving a prison sentence for domestic assault, paid for lavish gifts for his girlfriend Shantel Jackson’s birthday party in Las Vegas.

Shanel is used to the finer things in life, and she expects to keep benefitting from Floyd’s generosity even if he’s in prison. Floyd knows that he must keep his gold-digging girlfriend happy if he doesn’t want another baller to step in.

Mayweather splurged on a birthday cake designed to look like a $30,000 Balenciaga handbag (right).

From the NY Post’s Page Six:

Mayweather, who’s serving a three- month sentence for domestic battery against an ex-girlfriend, paid for the 10-person dinner at N9ne Steakhouse at the Palms Casino Resort Wednesday night, where Jackson was presented with a cake in the shape of a $30,000 alligator Balenciaga bag. Mayweather also gave Jackson a diamond watch, bracelet and ring, which friend and dinner guest 50 Cent photographed and posted on his Twitter feed. Jackson, an aspiring actress, will star with Fitty in the upcoming movie “Freelancers,” which stars Robert De Niro and Forest Whitaker, due out in August. Fitty also acquired a New York promoter’s license for boxing last week, and recently founded TMT (The Money Team) Promotions with Mayweather. Reports swirled yesterday that TMT would promote fighters including Mayweather once he gets out of jail, which is expected to happen Aug. 3.
