Sarah Harding and Gavin hit the town

 GAVIN Henson took his perma-tan out for the mother of all bashes after getting egged on by notorious party animal Sarah Harding.

The two booze hounds were knocking back the good stuff until 5.45am.

We dread to think how rough Gavin, 28, felt when he turned up for his Strictly Come Dancing rehearsals the morning after. Ouch.

The Welsh rugby stud and the Girls Aloud sexpot partied away in London members-only club Mahiki.

We’re told: “Sarah was on top form. She attended three parties in a mammoth 10-hour bender, which ended up with

her and Gavin piling into a taxi home at nearly 6am.”

The blonde bombshell started her night at the DJ Hero 2 party in Shoreditch before moving on to swanky VIP club Whisky Mist.

She was joined by a host of other celebrities including Brian Friedman, 33, Donna Air, 31, The Saturdays’ Vanessa

White, 20 and rapper Chipmunk, 19, to celebrate the Dom Perignon launch of the new exclusive Andy Warhol-inspired bottle.

The boozy celebs managed to neck a staggering £57,000 worth of Dom Perignon champagne between them.

An insider revealed that ladies’ man Chipmunk had to ask the club for some extra security because he was constantly hounded by girls and didn’t really know how to handle all the attention.

Sarah, also 28, then went to Mahiki to meet Gavin for a boozy lock-in until the wee hours.

Our mole revealed: “Sarah and Gavin were having a great night together, although before anyone gets any ideas, Sarah’s long-term boyfriend Tom Crane was out with them too.

“The club had a private lock-in.

“So Sarah and her pals could carry on drinking and dancing until the sun came up.”

If Gav’s cha-cha-cha is a bit wonky on Strictly tonight, you’ll all know why.
