Melanie Sykes admits assaulting Jack Cockings
Television presenter Melanie Sykes has been arrested and cautioned for assaulting her husband at their north-west London home.
The 43-year-old spent Tuesday night in custody before admitting the offence and accepting a caution, police said.
Manchester-born Ms Sykes, who found fame in an advert for Boddingtons beer, married Jack Cockings, 27, in May.
He did not require hospital treatment, a Scotland Yard spokesman said.
The couple met on Twitter after he used the social networking site to ask her out on a date.
A Scotland Yard spokesman said: "Police were called at approximately 21:45 on Tuesday, 26 November, to a residential address in Hampstead following reports of an assault.
"A 43-year-old woman was arrested on suspicion of common assault and taken to a north London police station.
"She has since been given a caution for common assault."
A spokesman for Ms Sykes declined to comment.
Former model Ms Sykes has appeared on shows including Let's Do Lunch with Gino and Mel, The Big Breakfast and Today with Des and Mel.
She has two children from her marriage to Italian actor Daniel Caltagirone, which ended in 2009.
