Kylie Jenner's family disapprove of her dating Tyga again.

Speaking to US Weekly about the teen entrepreneur's on-off relationship with the 'Rack City' hitmaker, a source said: "He's really not good for Kylie. The family doesn't want him around."

However, it has also been reported the television personality's parents and siblings are not fazed by Tyga's presence because they don't think he will be around for long.

Speaking previously about the father-of-one - who has three-year-old son King Cairo with his former partner Blac Chyna - another source said: "Her family isn't too upset about Kylie and Tyga being back together. They don't think it's permanent."

This news comes after the couple appeared to confirm they are back together when they shared a kiss in the photo booth at Khloe Kardashian's party and posed together on Snapchat as they celebrated Kylie's half sister's 32nd birthday at Dave and Buster's restaurant, Hollywood, on Monday.

In the three photos, Kylie snuggled close to Tyga and planted a kiss on his cheek for the cameras.

Meanwhile, a source previously claimed the Kylie Cosmetics founder "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 and reports the musician has moved into Kylie's six million dollar mansion in California.
