TV presenter Dermot O'Leary has said he is "hugely flattered" to have been asked to front the Brits.

The 43-year-old could host the music awards show after Michael Buble, whose three-year-old son Noah was diagnosed with cancer, pulled out.

The star, who is also hosting Wednesday night's National Television Awards, told The Sun it would be a "tough gig".

"Obviously it's hugely flattering to be asked," said The X Factor presenter.

"I'd much rather be asked in different circumstances, though. We should not forget in all of this that a little boy is really ill and his dad's got to take some time off to look after him.

"I'm not saying that in a schmaltzy way, it's obviously very important. That said though, it's a really tough gig and it's a huge gig to be asked to do."

O'Leary said he will be focusing on the National Television Awards - when he will open the show with Sir Tom Jones - before he considers the request to host next month's Brits.
