Singer-songwriter Bruno Mars has delighted fans around the world by sharing a photograph of himself taken in the early 90s. 

The 'Grenade' hitmaker, who was born in 1985, took to social networking site Twitter earlier this evening (February 27) and uploaded the picture accompanied by the tag line "Pimpin' since 92'. 

Although he hasn't made any further comments on the adorable snapshot, he retweeted an amusing remark from producing partner Ari Levine of The Smeezingtons that simply read: "u kinda resemble willow smith hahahahahahahaha"

2012 has been a successful year for Mars so far as earlier this month he won the International Male Solo Artist BRIT Award and back in January his debut record, 'Doo Wops and Hooligans', returned to the top of the UK albums chart.
