A former beverage manager at the Hard Rock Hotel in Las Vegas has sued Dennis Rodman, claiming the former NBA star assaulted her in March 2006 by rubbing up against her body and slapping her on the buttocks.

In her federal lawsuit filed this week, Sara Robinson also accused her former employer of retaliating against her after she complained about Rodman's behavior.

Rodman spokeswoman Shannon Barr declined to comment Saturday.

In her complaint, Robinson said she was working in the resort's Cuba Libre bar when Rodman, a hotel guest, began "making a scene" by trying to climb atop the bar after failing to gain her full attention.

"As Robinson stepped around the bar, Rodman grabbed her, pulled her towards him and rubbed his body against hers," the lawsuit alleges. "Robinson tried to get free from Rodman's grasp at which time he assaulted her by reaching down and slapping her open-handed on the bottom."
