British pop star Gareth Gates has gone public with his new girlfriend, just months after their close relationship was rumoured to have prompted the breakdown of his marriage.

The singer-turned-theatre performer split from his wife Suzanne Moles, the mother of his young daughter, 10 months ago amid allegations he had fallen for Faye Brookes, his co-star in West End show Legally Blonde.

Gates has now confirmed he is dating Brookes by turning out to support her at the opening night of her new stage show, The Sound of Music, in London on Tuesday (06Aug13).

He tells British newspaper the Daily Mirror, "I was here tonight to support my girlfriend Faye... I'm really proud of her, she's amazing."
