In addition, Smith recounted one sexual encounter she had with James after the two took a ride in one of his cars and discussed artwork on his office walls.
"I said, 'Well, I guess I should get going,' and he said, 'You don't have to,' and moved his chair closer to me and started rubbing my leg," she told Star, the Daily News reported.
"We ended up having sex on his couch."
Last week, James was accused of allegedly carrying out an 11-month affair with tattoo model Michelle "Bombshell" McGee while Bullock was in Atlanta filming The Blind Side -- for which recently won the Oscar for Best Actress.
Bullock reportedly left the house she shares with James two days before the initial reports that he had an affair with McGee surfaced but has denied more recent reports that she has begun talking to divorce lawyers.
James has apologized to Bullock and his three children from his two previous marriages while also claiming the "vast majority" the allegations against him are "untrue."
