The Met Gala is finally here, and fashion’s fiercest celebs are stepping out on the red carpet in NYC to strut their stuff — but the best accessory of all is some sexy arm candy.The Metropolitan Museum of Art Costume Institute Gala is celebrating its 65th year kicking off the museum's yearly fashion exhibit at the Costume Institute, and everyone who’s anyone will be attending— including some of Hollywood’s hottest couples.Check out which A-list power pairs In Touch is eager to see in their Met best:Kim Kardashian and Kanye West:The parents-to-be will rock the red carpet at tonight’s ball, where Kim will make her Met Gala debut. The star is said to have altered her dress five times for the fancy affair in order to fit her growing baby bump! The mommy-to-be, who was once rumored to be purposely left off of the guest list, was apparently invited this year since her beau will be performing.Beyoncé and Jay-Z:Blue Ivy’s parents are bound to make her proud tonight! Bey, who was named as an Honorary Chair of the Ball, stunned fans last year in a black lace Givenchy number that showed off her immaculate post-baby body. Jay, who knows a thing or two about ‘Suit and Tie’ style, will likely show up on his lady’s arm for support— undoubtedly, looking dapper as usual.Jessica Biel and Justin Timberlake:It was at least year’s Met Ball that Jess and JT made their first official post-engagement appearance— and the pair are supposed to be attending tonight’s swanky party, as well. In 2012, Jessica turned heads in a patterned Prada gown and showed off her new bling, while her now-husband Justin rocked a classic Tom Ford tux with a bowtie. Kristen Stewart and Robert Pattinson:Now that the Twilight couple have reunited in the states after Rob filmed a new flick in Australia for several months, the pair are rumored to be attending the gala. We can’t decide if we’re more excited to see if they attend or if Kristen, who has surprised fans with her elegant fashion transformation over the past two years, will show up in another winning ensemble.Jennifer Lopez and Casper Smart:We’d be lying if we said we weren’t eager to see what J.Lo will wear to the Met tonight, as the curvy star rarely has a red carpet miss. The catch: It will be hard for the singer to top her Met Ball look from 2010, where she stunned in a sequin-dusted Zuhair Murad Haute Couture strapless gown and Cartier Jewels. Hopefully her beau, Casper Smart, adds a nice “visual element” to her look!Gisele Bündchen and Tom Brady:In 2012, the mom of two rocked a Givenchy Haute Couture gown by Riccardo Tisci— who’s also serving as a co-chair of tonight’s event— but it was her show-stealing kiss with hubby Tom that left others oogling. The supermodel and her man are sure to turn lots of heads again this year on the red carpet.Which couple are you most excited to see at the Met Ball?Be sure to follow us @intouchweekly while we live tweet the latest in celebrity arrivals, style reveals and more from the Met Ball red carpet at 7 p.m. ET.
