Jonathan Ross is facing fresh criticism after suggesting parents should put their sons up for adoption if they wanted a Hannah Montana MP3 player.

The broadcasting watchdog in Britain received some complaints claiming the comments which he made on his Radio 2 show last Saturday were homophobic.

48-year-old Ross was involved in a discussion about prizes in a competition themed around the fictional teen pop star when he joked: "If your son asks for a Hannah Montana MP3 player, you might want to already think about putting him down for adoption before he brings his...erm...partner home."

A spokeswoman for Ofcom was unable to say how many people had complained but said: "We have had complaints. We are assessing those complaints against the broadcasting code."

Ross was banned from the airwaves by the BBC for three months after being involved in the Andrew Sachs lewd phone calls row.

He was suspended without pay in October after he and fellow DJ Russell Brand left obscene messages on Sachs's answerphone, which were broadcast on Radio 2.

A BBC spokeswoman said: "The BBC has received four complaints about Jonathan's comments on Saturday's show.

"However, these off-the-cuff remarks were made purely in jest and were not intended to be offensive. Jonathan is not homophobic in any sense and never meant for his comments to be taken seriously."
