The reality star, 18, posted a trio of pics with her on-again boyfriend on Snapchat on Tuesday, June 28, that showed her cozying up with the "Rack City" rapper, 26, and giving him a kiss on the cheek.
The affectionate photo booth pics appear to have been taken at Khloé Kardashian's birthday celebration with the Kardashian-Jenner clan at Dave & Buster's in L.A. on Monday night. The shindig capped off a weekend of togetherness for the pair, who are moving so fast that Tyga is even crashing at Jenner's new L.A. home.
"They are officially back together and he is staying there with her," an insider tells Us Weekly. "It's up in the air if he is going to live there permanently or is just staying there for now."
And for the time being, Jenner's family isn't chiming in on the new living situation.
"Her family doesn't care because they don't think it will last," the insider continues.
The lipstick queen, who split from Tyga in May, brought him along as her date to the premiere of Kanye West's NSFW "Famous" video at The Forum in L.A. on Friday, June 24, where they were seen holding hands.
Earlier that day, Tyga had posted and then quickly deleted an Instagram photo of the Keeping Up With the Kardashians star sitting on a bed in a skintight dress with the caption, "They always come back … ." She posted a similar image to her account, tagging the rapper on her bottom.
The PDA came just one day after she was pictured getting hot and heavy with rebound guy PartyNextDoor in his sexy new video for the track "Come and See Me."
Tyga and the reality star's reunion continued on Saturday when they were seen at L.A. hotspot 1 Oak, and the rapper chauffeured Jenner in the $320,000 white Ferrari he'd gifted her for her 18th birthday.
"They were together the whole night," an insider told Us of their date night. "Kylie was hanging with Tyga and dancing around him. She wasn't hanging with anyone else. They definitely looked back together."
