Rob Kardashian kicked off his 29th birthday with his girlfriend and her son, King Cairo, for a fun-filled day at Lego Land. The two were all over Instagram and SnapChat documenting their adventurous time together at the amusement park. After Lego Land, they all went out to eat as a happy little family together where the now-skinny Rob was spotted chomping down on a healthy salad.

It looks like Blac Chyna is a good influence for Rob after all! Still an awkward situation but hey, can’t win ’em all. See the cute pics from Rob’s pre-birthday celebration with Blac Chyna and King Cairo in the gallery!

I wonder how Tyga and Kylie feel about all of this… super weird! Somebody call Jerry Springer.
