Kim Kardashian broke with tradition last night - by gatecrashing her fiance Kris Humphries's stag do.
The reality star, who was also throwing her hen night in Las Vegas, nipped across to Kris's party to steal a secret kiss.
The couple were both hosting separate parties in Sin City - but despite vowing to stay apart on their bachelor/ bachelorette weekend, 30-year-old Kim couldn't resist paying him a visit.

After celebrating with her sisters Khloe and Kourtney, mother Kris Jenner, and friends at Tao Las Vegas, the curvaceous TV star headed to Lavo.
There she joined her fiance in his exclusive VIP corner for 10 minutes, before departing and leaving him alone with the boys.
Kris was joined by Kim's brother Rob, as well as Khloe's husband Lamar Odom, Kourtney's other half Scott Disick and several other NBA players.
Kim looked immaculate in a low cut beige leather dress, which she teamed with peep toe heels and all the accessories, including a tiara and a sceptre.
And it was a riotous evening, which saw the television personality quaff champagne, while being entertained with a few surprises.
