Rob Kardashian, Blac Chyna Enjoy Pre-Birthday Legoland Outing With Her Son King Cairo: Pics!

Babes in Legoland! Rob Kardashian and Blac Chyna certainly aren't sick of each other following their Jamaican vacation. The pair took a trip to Legoland in Los Angeles on Wednesday, bringing along Chyna's son, King Cairo, whom she shares with her ex (and Kylie Jenner's beau) Tyga."Pre Birthday Turn up," Kardashian captioned a photo with his new love the day before his 29th birthday.The birthday boy also posted a sweet snap of both him and Chyna with their heads inside of a giant Lego lion's mouth. The couple was all smiles during the outing as King Cairo, 3, enjoyed the park with them.

Chyna shared several photos of her little man, carrying around his Peppa Pig doll and doing a "secret hand shake" with his mom.Things seem to be going well for Kardashian, who prior to his relationship with Chyna had remained out of the public eye for years, famously skipping his sister Kim Kardashian's European wedding to Kanye West in May 2014.

And though he's dating the ex of his younger sister Kylie Jenner's current boyfriend, Tyga, the siblings are seemingly still on good terms. The pair appeared in a Snapchat together earlier this week, and when one site posted that the pair had reunited, Jenner shot back on Twitter, "I see him all the time chill."

"The family is really happy that they're together," a Kardashian source previously told ET. "The changes Rob has made in his life are so good. They appreciate Chyna for that. They're hoping this lasts for longer."
