Pink dumps her husband... for a girl!

5/11/2007 11:22:00 AM, The Fix Prev Next Looks like the dream is over for Pink and her motocross champion hubby Carey Hart.

Hot on the heels of rumours that Carey was playing up on his missus, Pink was spotted in a passionate lip-lock with a sexy friend.

The pair have described their marriage in the past as being an 'open relationship' - but apparently these drunken hookups are taking their toll on the couple's 22-month marriage.

And Pink's hookup in particular is raising questions about her sexuality.

'She was flirting the way you’d expect her to flirt with a man, cuddling and being overly affectionate,' hotel guest Kelly Bence said of Pink's latest fling. 'Pink was all over her friend. They were making out.'

As per most female celebrities with short hairstyles and muscular physiques, Pink has been swamped with lesbian rumours since the beginning of her career.

Pink’s rep denies the latest girl-on-girl rumour, but the source claimed the singer and her gal pal 'left arm in arm... and Pink got really drunk.'
