Colton Underwood's got an interesting choice of gym buddies as his season of The Bachelor wraps up.

The former football player still has a week and a half to go before fans find out who he ends up with on The Bachelor's two-night season finale on March 11 and 12. Underwood's outing on Thursday, however, has fans wondering what's to come, as he was photographed leaving a gym in Altadena, California, with actor Gregg Sulkin.

Sulkin, 26, is known for his roles on Wizards of Waverly Place, Faking It and Runaways, but he's also dating the sister of one of Underwood's frontrunners, Cassie Randolph. Sulkin and Michelle Randolph, 21, went public with their relationship in October 2018. Michelle appeared on the Feb. 25 episode of The Bachelor, during Cassie's hometown date.

Fans took to Twitter to react Underwood possibly spoiling that Cassie gets his final rose, though as one user noted, the blonde beauty is seen crying in a car -- which could imply she left the show -- in a promo for next week's Bachelor episode. Plus, since becoming Bachelor, Underwood is now a celebrity himself -- so maybe he and Sulkin know each other through another connection.

Cassie, Hannah Goodwin and Tayshia Adams are still left fighting for Underwood's heart on the ABC dating series, after the Bachelor shockingly said goodbye to frontrunner Caelynn Miller-Keyes following hometown dates. She was the only woman to tell Underwood so far that she was in love with him. Cassie, meanwhile, has yet to express that she's even falling in love with Colton.

"I don't think that's a fair question [to ask about sending Caelynn home over Cassie]. I think you can ask why Hannah, why Tayshia and why Cassie over Caelynn," Underwood told ET at the "Women Tell All" taping last month. "... it was nothing [about] where our relationship was. It was where the others were."

"That was the hardest rose ceremony that I had all season," Colton added.

The Bachelor airs Mondays at 8 p.m. ET/PT on ABC. The "Women Tell All" special will air on Tuesday, with the two-night finale airing Monday, March 11, and Tuesday, March 12. Join ET's Bachelor Nation Facebook group here.
