Lisa Berger, the president of entertainment programming for E! Entertainment, has resigned, a spokeswoman for the network told TheWrap on Friday.

Berger, who had been with E! for nine years, was responsible for massive hits as "Keeping Up With the Kardashians," "Chelsea Lately" and "The Girls Next Door."

“After nine wonderful years at E!, I have made the difficult decision to leave my post as President, Entertainment Programming," Berger said of her resignation. "My time at E! has been an amazing experience both professionally and personally, and it is hard to sum up nearly a decade of show launches, milestone moments and incredible friendships."

Berger added that she is "extremely proud of all of our accomplishments taking the network to record heights and forever grateful to my team whose talent and dedication knows no bounds.  Although it won't be easy for me to say goodbye, I look forward to sharing the news of my next challenge in the months ahead.”

E! President Suzanne Kolb said that Berger will "be dearly missed," noting that her "talent and creative vision have been invaluable to the success of E! over the past nine years."

Prior to E!, Berger worked at Fox Television Studios Productions, where she was instrumental in bringing the hit drama "The Shield" to FX.
