Justin Bieber isn't planning anything ''too crazy'' for his birthday.

The 'Never Say Never' hitmaker - who is dating Selena Gomez - turned 18 today (01.03.12) but insists he won't be indulging in any wild celebrations.

He said: ''My birthday, I'm going to hang out with my friends and family, have a little get-together; nothing too crazy.''

The Canadian singer was given an eco-friendly luxury Fisker Karma sportscar by his manager Scooter Braun during an appearance on the 'Ellen Degeneres Show' last night (29.02.12) but he is most impressed by a different gift.

Asked what his best present was in a twitter chat with fans for MTV News, he said: ''I got a pool table, a purple one and it's amazing. That's probably my favorite.''

While he is happy with his gifts, Justin has asked fans who want to mark the occasion to donate to charity rather than send him something.

He tweeted: ''i want to use my bday to help others. if u want please donate $18 to @charitywater on my 18th bday! (sic)''
