Nick Lachey is on the verge of tying the knot with longtime love Vanessa Minnillo, but first, 30 of the groom-to-be's friends made sure he enjoyed a classic Las Vegas bachelor party weekend.

On Friday, the 37-year-old 'Sing-Off host partied at TAO nightclub. In a casual white T-shirt, he mugged for paparazzi while showing off his black and red cake, featuring a ball-and-chain complete with "Property of Vanessa" stamped on top. Saturday included beach time and champagne, according to RadarOnline.

Guests spotted at the party included Jeff Timmons (former 98 Degrees vocalist and current Chippendales stud) and Houston Texans quarterback Matt Leinart.

Lachey has been keeping his wedding date mum, but his brother and best man, former 98 Degrees bandmate Drew Lachey, recently hinted: "It could be any day now."
