Lance Bass is living out his dream!

On Wednesday, the *NSYNC alum, 44, shared a photo of his family's Halloween festivities as they left to go trick-or-treating. Posing for a photo, the family of four showed off their costumes. Bass went as Kristoff from Frozen, matching his husband Michael Turchin, 36, who went as Sven.

The couple's daughter, Violet, looked adorable in a Snow White costume complete with a bow in her hair, while their son, Alexander, went as Spengler from Ghostbusters.

"I’ve dreamt of this moment for 4 decades!!! Happy Halloween from Kristoff, Sven, Snow White and Spengler!! (Everyone should have to dance for their candy btw)," Bass wrote on Instagram.

In July, Britney Spears shared photos of her meeting Bass' twins, posting the photos on X, formerly known as Twitter.

“I’m a new auntie for Lance’s babies !!! They are absolutely gorgeous babies !!!” Spears wrote.

As seen in both of the sweet snapshots, Spears happily smiled as she held each twin in her arms while Bass, carried the respective other. The singer’s estranged husband, Sam Asghari, was also pictured standing next to Spears.

In May, Bass spoke exclusively to PEOPLE, opening up about how he's been getting outdoors with his twins. "We've been getting in a lot of core memories lately, that's for sure," he said. "Now that the weather's great, we're spending a lot of time outside."

To his parents' surprise, Alexander has been enjoying exploring playgrounds and slides.

"I thought he was too young for that but definitely not," Bass shared. "He immediately went to the big boy slide and went head-first down. I can't believe he was that brave, but he loved it. I have a fearless boy on my hands."

Last Christmas, Bass and Turchin shared photos on Instagram of their Christmas celebration with Alexander and Violet.

In the cute snaps, both twins took turns admiring the Christmas tree and a plate of milk and cookies left out for Santa Claus. Both babies wore adorable holiday onesies, one printed with reindeer and the other with Santa's cookies, as they celebrated their second Christmas.

"🎶…. cause Santa Claus comes tonight! 🎅🏽," Bass captioned his post.
