Heidi Klum was spotted at LEGOLAND over the weekend with her three children, Leni, Henry and Johan to celebrate Johan’s second birthday. Kids’ toys have become increasingly techno-savvy, so it’s great to see Heidi Klum celebrate her son’s birthday with a trip to the theme park centered on this retro toy.

LEGO has achieved cult iconic status, and dedicated builders from all over the world continue to create incredible LEGO builds well into adulthood. This cluster celebrates the best, biggest and most detailed.

As Heidi Klum can attest, LEGOLAND in Carlsbad, California is one of the biggest examples of a large-scale LEGO build. But the LEGO skyscraper in Windsor, UK is an equally impressive architectural creation.
