From Sin City to NYC, celebrities have some major party plans this weekend.
In fact, one of these eligible dudes is planning bicoastal bashes for the big holiday, while another will be showing off his fine physique at a pool party...
We hope Nick Lachey got some rest this week, because he's got one busy weekend ahead of him.
First, Vanessa Minnillo threw her boozy bachelorette blowout in Vegas, and now it's Nick's turn. The former boy bander is having his bachelor party tonight at Tao nightclub, and if it's anything like his bride-to-be's, we expect him to be feeling hungover on Saturday.
After Vegas, Nick's off to NYC to host Macy's Fourth of July extravaganza Monday, where Beyoncé and Brad Paisley will perform.
Also celebrating in Las Vegas is Scott Disick, who's throwing a party at Chateau nightclub on Saturday. We assume baby mama Kourtney Kardashian might chaperone join him as well.
Rihanna will also let loose in Sin City at Nikki Beach after her Loud tour concert that night.
Back east, Twilight vamp Kellan Lutz is attending Ciroc's Cabana Club pool party at a private mansion in the Hamptons. We're betting he'll bare those famous abs of his, while Reverend Run deejays.
One VIPartier who we likely won't see in the Hamptons? Lindsay Lohan.
The birthday girl was on the list for the L.A. Takes the Hamptons bash, but she's since been removed.
We trust she'll be living it up no matter where she decides to celebrate.
