Kristin Stewart, 22, and married director Rupert Sanders, 41, were caught having an affair.

 UPDATE: US Magazine has published the scandalous photos online.

The “Twilight” love nest has been rocked by a cheating scandal, and an even more shocking apology. The cheater, Kristin Stewart, was busted by Us Weekly when photos surfaced of Stewart with director Rupert Sanders. The actress’ camp has issued an apology to People magazine while denying the appearance of romance and calling the incident a “momentary indiscretion.”

“She wasn’t having an affair with Rupert. It was just a fleeting moment that shouldn’t have happened,” insiders told the magazine.

Kristin Stewart and boyfriend Robert Pattinson were together at the Teen Choice Awards, after the cheating scandal broke.

Sanders, 41, is married to Liberty Ross, a British model. The couple has two children. “I am utterly distraught about the pain I have caused my family,” Sanders tells People in an exclusive statement.

“My beautiful wife and heavenly children are all I have in this world. I love them with all my heart. I am praying that we can get through this together.”

Stewart, 22, is said to “feel awful” about the incident. She and her boyfriend, “Twilight” cast mate Robert Pattinson, were spotted together after the Us Weekly photos surfaced.
