American talk show hostess Wendy Williams has reportedly lashed out at “Twilight” starlet Kristen Stewart for cheating on Robert Pattinson. She expressed her doubt over the “pain” Stewart witnessed when she broke-up with Pattinson.

“Kristen did you forget that Rob dumped you because you were cheating with your director, Rupert Sanders, who was married?!” Williams told Life & Style magazine's Oct. 5 issue, Classicalite reports.

Williams didn’t end her criticism here. She further alleged that Stewart is using Pattinson's name to benefit her own career. “I know Kristen needs all the press she can get now that her Twilight days are over, but it’s obvious she’s only talking about Rob to stay relevant…” Williams said. She advised the Cesar Award winning actress to “stop reliving the past and start rebuilding your acting career.”

Pattinson and Stewart broke-up in 2012 when Us Weekly published photos of the actress kissing her “Snow White and the Huntsman” director Rupert Sanders. Sanders, who was married to model Liberty Ross at that time, also later divorced from her. Stewart also issued a public apology for her cheating via People magazine saying she was “deeply sorry for the hurt and embarrassment” she caused to people because of her “actions.”

Stewart opened up about her “painful” break-up with Pattinson in a recent interview with the Daily Beast. The actress revealed that she used her pain and anger to act as Nia in her upcoming film “Equals.” In the movie, Stewart acts alongside Nicholas Hoult. The two play a couple who fall in love for the first time in an environment where love is forbidden.

In her previous interview with Marie Claire, the actress admitted that she did everything intentionally. “I lit my universe on fire and I watched it burn,” Stewart told the magazine about her cheating scandal.
