"American Idol" judge Simon Cowell has reportedly been seeing another woman behind the back of his girlfriend, former model Terri Seymour.

The Daily Mail said that the 46-year-old BMG executive was recently seen out with 21-year-old society girl Jasmine Lennard and that she has made numerous visits to Cowell's home when Seymour was away.

"They spend most of their time together in Simon's house when Terri is at their other home in Los Angeles," a source told the Mail. "Sometimes they go out, but only with other friends so as not to arouse any suspicion."

While Cowell has admitted in the past to looking at other women, a spokesman for the famed entertainment judge has said Lennard's visits to his home were entirely business-related.
