London: Singer Ryan Lee of the popular boy band `Blue` has been charged with assault after allegedly hitting his fiancee, Samantha Miller.
The `One Love` hitmaker is accused of attacking the 26-year-old, who is also the mother of his young son, Rayn.
The incident took place as the couple drove through London`s West End on Wednesday night and Lee was charged and arrested the next day, said the police, reported Daily Mail online.
"Lee Ryan, 27, self-employed, of Henley-on-Thames, is due to appear on bail at court on Friday August 27 charged with common assault," a Metropolitan Police spokesman said.
But the singer is denying the charges.
"Lee 100 percent denies common assault. He categorically did not hit Sammi and will be fighting these charges in court," his spokesperson said.
The incident comes a year after the couple were pictured having an explosive row in the street. Lee was photographed shouting at his fiancee outside the Mayfair Hotel before thrusting a fist full of bank notes at her.
The couple have been together since Autumn 2007 after meeting on social networking site MySpace.
Miller gave birth to their son Rayn Lee Amethyst, just a year after they first met.
Their relationship suffered another blow last year when it emerged that Lee had fathered a secret love child three years ago.
Lee and bandmates Antony Costa, Duncan James and Simon Webbe enjoyed hits such as `All Rise` and `One Love` along with a duet with Elton John on a cover of `Sorry Seems to be the Hardest Word`.
The group sold 3.5million records before splitting in 2005 but have since reunited and are recording a comeback album.
