The Terminator took over Sin City.

Arnold Schwarzenegger spent the weekend in Las Vegas to celebrate his son Patrick's 21st birthday. A source tells E! News that the duo dined at Strip House at Planet Hollywood Resort and Casino with family and friends, including sister Christina, on Saturday. At the end of the dinner, Robert Earl, Chairman and CEO of Planet Hollywood International, presented Patrick with a special birthday cake, custom created by Planet Hollywood's pastry chef.
 
Earlier in the evening, the group took a spin on the world's tallest observation wheel, the High Roller at The LINQ, where they enjoyed a private cabin with a Sky Bar and their own personal bartender.

Sounds like the perfect way to ring in a milestone year!

On Friday, Patrick got to indulge in yet another tasty treat in honor of his special day at Hakkasan restaurant and nightclub at MGM Grand Hotel and Casino.

The former California governor posted a sweet (and slightly inappropriate but super funny) throwback photo in honor of his son's birthday on Instagram. The snapshot showed Arnold and his two boys, um, releasing themselves at a urinal, and paired the pic with a caption that read, "Happy birthday to a great son who has grown into a great man, @patrickschwarzenegger. I'm so proud of you and I love you. #tbt"

So precious.
