Singer/songwriter Bruno Mars' second single is released in the UK today (January 10).

The follow up track to 'Just The Way You Are', which shot to number 1, is 'Grenade'. The balladic number has already hit the top spot on the U.S Billboard chart and is expected to reach a similar height overseas. 

Mars, real name Peter Hernandez, has also revealed that he will perform at Dublin's Olympia Theatre on March 9 following a tour of mainland Europe although no gigs for England have yet been announced.
