The 'Ridiculous 6' actor called on some of his famous friends in his first video post.
Taylor Lautner is going back to December.
The Ridiculous 6 actor referenced his long-ago romance with Taylor Swift in his very first -- very meta -- Instagram post, offering up her phone number to David Spade in exchange for a cameo appearance in the clip.

The 60-second video opens on Lautner pitching pal Adam Sandler his idea for the Instagram video, suggesting he show off his gymnast skills with a slow-motion backflip.
"I've seen you do that before," Sandler deadpans. "Maybe something else."
Sandler goes on to shut down all of the former Twilight star's suggestions, including "dabbing" ("I don't like seeing you do that, that's gross") and a cameo appearance ("I would, but the dog doesn't want me to").
Enter Spade, who also wants nothing to do with the "dabbing" dance craze.
"It's just not my thing," he says, before Lautner suggests: "I'll give you Taylor Swift's cell phone number."

Mission: accomplished?
"Hello, Instagram! It only took me until the year 2016 to finally join," Lautner quipped in the video caption, while his bio simply states: "Better late than never."
Meanwhile, his former flame boasts more than 77.5 million followers on the social media site.
Swift and Lautner dated briefly after co-starring in the 2010 romantic comedy Valentine's Day. Swift was famously rumored to have written her hit, "Back to December," about their breakup. The singer added fuel to the fire during a 2011 concert in Los Angeles, dedicating the song to "the boy from Michigan" (Lautner hails from Grand Rapids) and making her way to the audience to give him a hug.
But all that's ancient history! Swift has been dating EDM superstar Calvin Harris for more than a year and couldn't help gushing over her beau in an interview for the May issue of Vogue. Watch below.
