Kourtney Kardashian in for a passionate kiss...but Kris Jenner

She is known for being a hands-on mother, even earning the nickname 'momager' for managing her children's careers.


And it seems Kris Jenner still needs to learn when to back off.

The 57-year-old is seen flashing a peace sign as Scott Disick pulls Kourtney Kardashian in for a passionate kiss at Kylie Jenner's sweet sixteenth birthday party on Saturday in Los Angeles.

The Keeping Up With The Kardashians star is seen grinning as she photobombs the image of  34-year-old daughter and Scott, 30, sharing a smooch.

Kris wore an unusual all-black ensemble - replete with fingerless gloves - for the Alice In Wonderland-themed party at LA's AT&T Center.

Kourtney, meanwhile, donned a flirty black-and-white dress while Scott looked suave in a silver-blue suit.

The entire Jenner and Kardashian family - minus new mother Kim, who was attending Kanye West's grandfather's funeral - were in attendance at the lavish soiree.

Sisters Kendall, 17, and Khloe, 29,  both got into the spirit of the theme by wearing cute headgear.

Kendall, 17, who is just one year older than Kylie, arrived looking chic in a black maxi dress slit to the thigh.
