The supermodel delighted the sell-out crowd by taking to the stage at Pete’s first show since he checked out of rehab for drug addiction.

Kate, sporting a black sweater mini-dress, and Pete belted out the track ‘La Belle et La Bete’ - which translates as ‘Beauty and The Beast’.

One fan said: “It was a fantastic moment. Everyone went wild. Kate looked sensational - and she sounded great.”

Pete, 27, had only checked out of London’s The Priory clinic for cocaine and heroin addiction earlier that day. The Babyshambles frontman was seen sipping water while Kate enjoyed a bottle of lager.

Kate, who exited the stage after one song to take photographs of the band, left the crowd screaming for more at Carlow’s Music Factory, Ireland.

The 32-year-old model also ignored Ireland’s strict smoking ban in public places by chain smoking throughout the show.

Babyshambles were scheduled to play another sell-out concert at Dublin’s Ambassador last night (26.09.06).

Kate reportedly ditched her luxury five star hotel suite to stay with Pete and the band on the tour bus.

When asked about the possibility of the pair marrying in Ireland, Pete blushed and said: “No comment.”
