Lothario Russell embarks on a brand new holiday romance

The 33-year-old comic actor and television presenter was seen enjoying a break in Mexico with 22-year-old Australian actress Teresa Palmer.

And in true Russell Brand style, he took to the beach in a pair of shorts that were even briefer than his female date's.

Lothario Russsell was spotted looking very serious about his new love as he waded through the surf with his arm around Teresa.

The 22-year-old actress, previously starred in 2007 film December Boys with Harry Potter actor Daniel Radcliffe, who she shared a steamy love scene with, and horror film The Grudge 2.

She has dated OC actor Adam Brody, and split from her retired Australian Football League player boyfriend Stuart Dew in March 2007.

An onlooker spotted the duo and said: "They looked like any loved-up couple on holiday. If I didn't know about Russell's reputation, I'd be sure it was serious."

But taking the star's reputation into account - he has dated Kate Moss, and Big Brother contestant Kate Lawler among others, it may not be worth putting any money on it.

Brand recently signed a £1.8 million two book deal with HarperCollins, with the first book due out for Christmas.

He told The Sun: “The new book's philosophy, yes, but more Clarkson than Kierkegaard.

'I'll pontificate on subjects as diverse as West Ham, Morrissey and tea-bagging - all of which are potent ontological metaphors.

'If I haven't solved the riddle of existence by chapter two I shall hurl the manuscript onto Nietzsche's grave and French kiss Bertrand Russell's corpse.'
