Pop star Nick Jonas refused to celebrate Valentine's Day until last year (14) when his views on romance were changed by his new girlfriend Olivia Culpo.

The former Jonas Brothers singer insists he shunned the most romantic date in the calendar his whole life until he spent 14 February, 2014 in the Dominican Republic with the Miss Usa 2012 winner.

He tells Cosmopolitan magazine, "Until last year I'd never celebrated it. People put a lot of emphasis on the day, which can be problematic, but last year Olivia and I and two of our friends went on holiday to the Dominican Republic, which happened to fall over Valentine's Day. That was awesome."
