RENO, Nev. —The woman suing quarterback Ben Roethlisberger for alleged sexual assault has been accused of bragging about having consensual sex with him to a co-worker.

According to court documents filed late Friday, Angela Antonetti said the woman who made the rape claim "did not appear to be upset, stressed-out or nervous" about her time with the Pittsburgh Steelers star during a 2008 celebrity golf tournament at Lake Tahoe.

Antonetti says her Harrah's hotel-casino co-worker "appeared happy and boastful" about it and later said she thought she might be pregnant from the encounter.

Lawyer Cal Dunlap, who represents the woman, declined to comment.

In her lawsuit, the 31-year-old Nevada woman says the two-time Super Bowl winner raped her, a claim he vehemently denies.
