Celebrity Sexy Seuss! Channing Tatum and Jenna Dewan-Tatum Attend Celeb-Filled Halloween Party as Matching Cats in the Hat They weren't the only costumed celebs at the bash, which also included Jessica Alba and Paris Hilton By Adam Carlson Published on October 31, 2015 10:35 AM Share Tweet Pin Email Photo: Vince Flores/StarTraks Channing Tatum and Jenna Dewan-Tatum were positively Seussian in the coordinated Cat in the Hat costumes they wore to Casamigos’ A-list Halloween party Friday. Channing, 35, opted for a classic look: big floppy hat, big floppy bow-tie and big floppy body suit. But not Jenna, 34, who accessorized her costume with black gloves, fishnet tights and thigh-high boots. (They both wore matching makeup, complete with black nose and whiskers.) The Tatums weren’t the only costumed celebs at the Beverly Hills, California, bash. George Clooney‘s former girlfriend Elisabetta Canalis dressed up as a sexy soldier; Jessica Alba dressed as Romy White from Romy and Michelle’s High School Reunion; and Alba’s husband, Cash Warren, dressed as Tom Cruise‘s Maverick in Top Gun. Also in attendance: Cindy Crawford (biker chick), Josh Duhamel (Karl Lagerfeld) and Paris Hilton (sexy viking), among many others. Check out Amal Clooney at Work! While Clooney wasn’t spotted outside his tequila brand’s annual bash, he has been keeping busy expanding his family with wife Amal Clooney. George and Amal adopted Mille, a 4-year-old shelter dog, from the San Gabriel Valley Humane Society on Wednesday – making her George’s second rescue pup.
