Celebrating his 29th birthday one day early, Rob Kardashian and his Blac Chyna hung out at Legoland of all places.

While it sounds random -- it turns out the Rob was hanging with his lady love and her son King Cairo at the theme park and miniature park located in Carlsbad, California.

For the theme park trip, Rob wore shorts, an oversized shirt and a big ole grin on his face. The 27-year-old opted for some sporty colorful Adidas leggings and yellow athletic shoes.

In one of the snaps, Rob wrote, "🎉 Pre Birthday Turn up." It looks like the couple were turning up the fun with before Rob's birthday today.

It also looks like former recluse is stepping up to be a really good step dad!
