Kylie Jenner enjoys family outing with Tyga, his son

LOS ANGELES, July 25 (UPI) -- Kylie Jenner enjoyed a family outing with boyfriend Tyga and his son, King Cairo, on Sunday.

The 18-year-old reality star spent the day with the 26-year-old rapper and his 3-year-old son at Six Flags Magic Mountain in Los Angeles. Tyga shares King with Blac Chyna, who is engaged to and expecting a child with Jenner's half-brother Rob Kardashian.

Jenner and Tyga both shared photos from the outing on social media. The reality star posted a picture of herself smiling back at the camera, while Tyga shared a snapshot of himself and King on a ride.

The Keeping Up with the Kardashians star and and her beau seem to be going strong following their recent reconciliation. The couple split in May but appeared to get back together the next month.

"[They are] definitely, officially, 100 percent back on," a source told E! News in June. "They needed a reset. Ky is happy. She feels like she needed the time apart but it's fate."

Kardashian, meanwhile, sparked speculation Monday after he erased all signs of Blac Chyna from his Instagram account. The 29-year-old reality star deleted his many photos of the model, leaving only one picture of himself from April.

Kardashian and Blac Chyna have been together since January. Blac Chyna's ties to Tyga initially caused rumors of a feud with Jenner, but the women dismissed such reports by sharing photos together in April.
