Over the weekend, Kylie Jenner celebrated her 16th birthday party, but Kourtney Kardashian and Scott Disick momentarily stole the spotlight from the guest of honor with a passionate kiss.

The "Keeping Up with the Kardashians" star, who is rumored to be pregnant with her third child, took a break from partying to give her guy a smooch.

However, during their picture perfect moment, the couple was photobombed by Kardashian's mother, 57-year-old Kris Jenner.

In the photo, taken at Kylie's Alice In Wonderland-themed party at LA's AT&T Center, Disick is seen pulling his girlfriend in close for kiss while the reality star's mother sports a wide grin while throwing up the peace sign.

The oldest Kardashian sibling recently made headlines after male model Michael Girgenti claimed that he was her 3-year old son Mason Dash DIsick's biological father.

After taking a paternity test, Kourtney Kardashian revealed to E! News that Scott Disick is indeed Mason's biological father. She said, "After three-and-a-half years of rumors and lies being spread by an individual I met briefly at a photo shoot, I am setting the record straight that Scott is Mason's father.

"While it saddens me to have to address these ridiculous lies-especially when the truth was never in doubt-this story must be put to rest."

Kardashian's attorney Todd Wilson previously told E! News, "This individual has been selling false and fabricated stories to the tabloids for years about Kourtney Kardashian and her son, Mason. Scott Disick is Mason's father.

"We have not seen the reported court filing, but we are informed that this individual has been seeking to get paid to publish his ridiculous pleading."

Wilson went on to say, "His claims are absurd and this is simply another shameful attempt to gain publicity and profit from fictional stories about my client."

A spokesperson for Girgenti told Radar Online that even though Disick submitted to a Paternity test proving he was Mason's father "We don't trust the results and believe it could have been fixed." They went on to say that they are "still going to court to fight for court ordered results."
