It was one happy Halloween for Justin Timberlake and wife Jessica Biel! The lovebirds threw a Halloween party at their home Friday night with an adorable couples costume and plenty of high-profile celebs in attendance.

The party was John Hughes-themed — think Pretty in Pink, Ferris Beuller's Day Off, and Sixteen Candles — and they donned matching pig costumes as a nod to the Griswolds in National Lampoon's European Vacation, a source told People. The insider also noted that Timberlake was "doting and sweet" to his Mrs.

Other celebs at the bash were Amy Adams, dressed as Long Duk Don from Sixteen Candles, a newly-single Jennifer Lawrence, Kate Bosworth and Andy Samberg.

While their star-studded get together is pretty exciting, the amount of affection between these two lovebirds lately is even more. Just recently, Timberlake and Biel jetted off to New Zealand where JT posted a rare but affectionate post with his wife on Instagram, aptly quoting what we now know is one of his favorite films. "'Life moves pretty fast. If you don't stop and look around once in a while, you could miss it.' --Ferris," he write alongside a photo of him and Biel sitting on a bench.

One reason he may be extra lovey-dovey lately? Rumors are floating around that Biel actually has a baby on the way! There have been a few street spottings recently where many people speculate they saw a possible bump. And then, last Thursday, Instyle's Editor in Chief Ariel Foxman dedicated his #tbt to Biel, writing: ""Congrats @jessicabiel on your impending motherhood. Looking forward to the red carpet maternity style pix to come #tbt." The post was shortly removed and his profile was turned private.

With all of these adorable gestures towards one another, recent speculation and social media blunders, we wouldn't be surprised if a little Timberlake were to enter the world soon.
