*Although he’s currently incarcerated, boxer Floyd Mayweather, Jr. ensured that his fiance Shantel Jackson, had a fantastic birthday.

She celebrated with girlfriends and rapper 50 Cent, dining at N9ne Steakhouse at the Palms, along with a private birthday party.

Lacing her with gifts, we hear she had a three-tiered cake (with a photo of her and Mayweather), a Balenciaga alligator bag (worth $30,000), Hines Couture shoes, jewelry and Balenciaga cake.

Peep the pix!
