Taye Diggs is the latest celebrity to be targeted in an alleged cheating scandal.
Star Magazine claimed Diggs is fooling around behind the back of Idina Menzel, his wife of 10 years.
But sources tell EnStars, "It is NOT true!"
According to the report, the actor was spotted with a sexy brunette at Emerson nightclub in Hollywood on June 19.
Star quotes a "clubgoer" as saying, "At 1 a.m., [Diggs] led her upstairs to the back of the club, and they began making out behind a pillar."
Earlier this week, a new TV spot for Universal Pictures' upcoming sequel, The Best Man Holiday, debuted. The film stars Broadway vet Diggs.
The musical comedy is set to hit theaters on November 15, 2013.
In the film, when the college friends finally reunite over the Christmas holidays, they will discover just how easy it is for long-forgotten rivalries and romances to be ignited.
