Nick Jonas threw Meghan Trainor a birthday party.

The 'Jealous' hitmaker hosted the 21st birthday celebrations for the singer at Tunney's Gallery at the Wynwood Walls in Miami, Florida.

The 'All About That Bass' hitmaker - who was surprised by the 22-year-old singer with a cake on stage at 93.3 FLZ's Jingle Ball - took to her official Facebook page to thank Nick and her fans.

She wrote: "Luckiest birthday girl in the world. Thank you Tampa and ‪#‎jingleball2014‬ for celebrating it with me and thank you Nick Jonas for everything (sic)"

Meghan recently revealed that she wanted to date a pop star - but Nick is certain to be off limits as he is dating model, Olivia Culpo.

The 'Lips Are Movin' singer admitted she struggles to find a boyfriend since she became famous because men are "intimidated" by her career.

She said: "Guys are scared of me, it's ridiculous.

"I guess it's because I'm a pop star now and they are intimidated. I'm finding it so hard to date.

"Then even if I find a guy I'm like, 'OK bye, see you in six months as I'm off on tour'. I am so down to date another pop star. We could be as adorable as Ariana Grande and Big Sean."

Meghan isn't feeling too positive about finding love, admitting that all the famous guys are already in relationships or her friends.

She added: "All of the guy pop stars are either my friends or are already dating.

"It's not like a rock star lifestyle any more - everyone has a lover. I want someone funny and nice. I don't care about age or looks."
