Nick Lachey and Vanessa Minnillo's wedding is getting closer, and that means it's time for the twosome to get showered with gifts—and, apparently, liquored up.

The couple threw a sunset wedding shower Sunday night, a rep for Nick confirms to E! News, and the groom-to-be partied hard, tweeting: "My liver is furious with me!! Great time last night at our wedding shower."

So who was on the list for the rooftop bash at the London Hotel in L.A.?

Nick's brother Drew Lachey and footballer Matt Leinart were two famous faces in attendance, and Nick even managed to work in some cross-promotion for the show he hosts. The Backbeats, an a cappella crew from season two of The Sing Off, performed at the party. Pretty crafty!

All of the guests seemed to be in full-on party mood, too, according to reports.

"Everyone seemed to have a great time. It was a laidback yet sophisticated atmosphere. Guests danced until the late hours," they tell People.

While the twosome surely scored lots of presents, you can still send them a congratulatory gift.

Wineglasses and a china set from their registry at Geary's hasn't been bought yet. They've also registered at Williams & Sonoma.
