Kardashian and Chyna have seemingly been co-parenting their seven-month-old daughter Dream amicably in recent months, but their dynamic has taken a turn towards romantic again, TMZ reported.
Kardashian, 30, has been living at his ex-fiancee's house for about one week now, according to the website.
The reality TV stars have reportedly been socializing with friends, enjoying family barbecues and pool parties, and going on hikes together since apparently rekindling their flame.
The couple just spent Father's Day together with Dream at Disneyland. Chyna reportedly bought Kardashian expensive gifts for the holiday -- including a Louis Vuitton bag, customized Dodgers hat, and sneakers with white and blue roses emblazoned with an "R."
Kardashian and Chyna, 29, are reportedly into each other again and the reunion isn't about fame, business, or a TV show.
Kardashian and Chyna had called it quits on their relationship for good circulated in February, but then they were spotted on a dinner date in late April at TAO restaurant in Los Angeles, when they also posted flirty photos on Instagram.
Despite prior reports Kardashian had been dating Mehgan James from Oxygen's Bad Girl's Club for several months -- which Kardashian ultimately denied -- the dad of one declared his love for Chyna on May 30 by posting sweet throwback photos of her on social media.
Kardashian and Chyna initially began dating in January 2016 and got engaged three months later in April of that year. They welcomed Dream in November.
The pair's volatile dynamic, however, led to frequent breakups -- with the most serious being a blowout fight around Christmas last year when Chyna left their shared home with Dream.
