Kylie Jenner and Tyga kiss at Khloe Kardashian's party

Kylie Jenner and Tyga appeared to confirm they are back together after they shared a kiss in the photo booth at Khloe Kardashian's party.

The 'Keeping Up With The Kardashians' star shared a picture of herself and her on-again, off-again beau posing together on Snapchat as they celebrated the 32-year-old television personality's birthday at Dave and Buster's restaurant, Hollywood.

In the three photos, Kylie snuggled close to the 'Rack City' hitmaker and planted a kiss on his cheek for the cameras.

Meanwhile, a source previously claimed the 18-year-old star just "can't resist" Tyga.

They said: "Kylie and Tyga are giving things another shot. They are taking things a lot slower this time around, though, and are using their former arguments and fights as a learning curve and as a reference point for a healthier future.

"She can't resist him and he can't resist her. They are still so in love, so getting back together was relatively inevitable. They both knew that but needed their space to decompress and regroup and grow."

The couple sparked rumours of a reconciliation when they showed up at Kanye West's 'Famous' video premiere in Los Angeles last week together but Kylie is said to be still officially "figuring things out".

An insider added recently: "Tyga seems more interested in getting back together than Kylie does. Kylie still seems to enjoy being single. She acts like she is figuring things out.

"But she likes Tyga's attention and the fact that she has the upper hand now. Tyga is working hard to get her back."

The news comes a week after Tyga claimed their relationship overshadowed his career.

He said: "When you're in a very public relationship like that, it's hard for other people to see you differently than that. Being in that it took a lot, career wise, everything. It overshadowed a lot of my talents and a lot of things that I worked hard for."
