While it's certainly a party when singer Miley Cyrus' name is included on the guest list, it's really a party when she's the guest of honor. On that note, the "Wrecking Ball" singer recently celebrated her 22^nd birthday with friends, and of course, her rumored new boyfriend, Patrick Schwarzenegger.

Apparently, Schwarzenegger and Cyrus have been dating for a month now and reports claim that their relationship is getting serious since Cyrus chose to celebrate her birthday with Arnold Schwarzenegger's son and with some of her closest friends.

It was a Happyland-themed party last November 22 at the Metropolitan Night club in West Hollywood where Cyrus, wearing her pink fur jacket and colorful outfit, was spotted walking outside the city towards the venue.

According to reports, Schwarzenegger even brought his guy friends to Cyrus' party and was sweet with the 22-year-old singer all night. "Brought a bunch of his guy friends who were tripping out on this party, they have never seen anything like it!" a source told US Weekly about Schwarzenegger's friends.

It was a sweet sight to look at according to several witnesses as Schwarzenegger and Cyrus were affectionate with each other. "Miley and Patrick were hugging and dancing together," the party source continued, "blended in well and was with her much of the time."

Meanwhile, as the party theme is said to be titled "Miley's Twisted Minds", Schwarzenegger wore a 'Top Gun' sort of outfit. The son of the former California Governor wore a pilot's jumpsuit as he was spotted together with his guy friends and Cyrus.

It was a special occasion and according to reports, Cyrus chose to be with Schwarzenegger because he was different from all the other guys she previously dated. "I have seen Miley with Liam and other boyfriends but honestly I have never seen her look as loved up as this," a source told E! News, "This is more than just a fling, they look like they are falling in love with one another," the source added.
