The Scooby-Doo stars spent some time at the Mauna Lani resort in Hawaii, soaking up the sun, celebrating the new year, and, perhaps, getting into a spot of mischief. Gellar shared a recap of their travels on Instagram yesterday Jan. 2, comprised of several solo shots alongside a couple of the happy couple. The first two photos featured a close-up selfie of Gellar with a series of palm trees in the background, as well as a full-body shot of the actress in a wispy black maxi dress in front of giant old tree on the beach. The third slide featured a cameo from Prinze Jr., leaning his head in close to touch foreheads with his wife, who wore a gold “Happy New Year” tiara. Next up was another selfie from the hotel bathroom, in which Gellar leaned down and looked off to the side, wearing a color-blocked blue bikini. There were also photos from a wine-infused boating trip, a ziplining adventure, a visit with Santa (featuring her iconic Barbie swimsuit), and a vague moment on the darkened beach in which Gellar wore a long, glittering dress, sans shoes, and waved a shred of white fabric or paper up in the air. “Vacation photo dump… will accept guesses for what I’m doing in the last one (you probably won’t get it right),” she teased in the caption. “You totally just got Lei’d 🤪,” former co-star Michelle Trachtenberg guessed. “You surrender?” asked Selma Blair. “Peeing in the bushes?!” one fan asked, while another joked, “Hoping the last one isn’t an actual ‘vacation photo dump.’” Gellar has yet to confirm or deny any guesses hazarded, and the two private accounts she tagged in the photo offer no context clues. Other commenters made joking comments about the actress’ Buffy character, but a few offered their compliments, too. “My favourite Hollywood couple for sure. Happy New Year!” one read in part. “Wow with all due respect Mr. Prinze Jr is one lucky man… Sarah is BEYOND beautiful and one fine-ass woman 😍,” another said.
