The *NSYNC member and author of kids book 'Trick or Treat on Scary Street' met his now-husband for the second time dressed in a "cheesy" last-minute costume

Lance Bass and Michael Turchin's twin son and daughter celebrated their third birthday in style Tuesday (Oct. 8). In photos shared to the *NSYNC alum's Instagram, the family of four got a jump start on the toddlers' birthday festivities - they don't actually turn 3 until Oct.

Lance Bass is channeling his boyband past to celebrate a special milestone in his children's lives. Bass and his husband Michael Turchin went all out for their twins Violet and Alexander's third birthday party,

Violet wears a purple sweatshirt and blue jeans, sitting next to her teal birthday cake, while her brother Alexander wears a gray sweatshirt and blue jeans, posing next to a red cake. The party featured new Tile Town playsets from Moose Toys, including the Tile Town Pet Clinic and Rescue and the Fire Station.
