Patrick Schwarzenegger parties harder than girlfriend Miley Cyrus, according to Cody Simpson.

The Australian singer, who was recently spotted hanging out with the new couple in Miami, Florida and Nashville, Tennessee, says the 21-year-old student is ''such a blast.''

He said: ''We met through a friend's party and stuff, he's such a blast. He's a good bloke.''

Asked whether Patrick or the 'Wrecking Ball' hitmaker, 22, parties the hardest, he also told gossip website TMZ.com: ''Honestly, Pat. Every time I see him we have such a good time.''

Meanwhile, the 17-year-old star, who recently reunited with his on-again, off-again girlfriend, Gigi Hadid, 19, is planning to enjoy a quiet Christmas in Los Angeles before jetting off to Dubai for a wild party on New Year's Eve.

The 'La Da Dee' hitmaker said: ''I'm spending it here, which is the first time in a couple of years so it'll be nice.

''I'm going to Dubai for New Year with some friends, so it should be pretty insane. It's going to be pretty fun.''

Cody decided to get back together with model Gigi last month following their split in May because she makes him ''a better guy.''

He previously told Confidential: ''I enjoy being with her because she makes me a better guy. She checks me when I slip up.''
