Caitlyn Jenner shares a kiss with her ex-wife Kris Jenner in new mid-season promo for "I Am Cait" Season 2. The retired Olympic gold medal-winning decathlete apologizes to the Kardashian matriarch during their trip to Mardi Gras with Caitlyn's squad.

Caitlyn kisses Kris on the lips when the two were on a bus. Caitlyn's friends cheer on the former husband and wife. The video then sees the 66-year-old reality star kissing her best friend Candis Cayne while they're enjoying dinner with friends.

Later on, Caitlyn and Kris sit down and have a heart-to-heart conversation. Caitlyn apologizes to her ex-wife for the way their marriage ended. "I just want to apologize for the way I acted," Caitlyn tells Kris in the video. "It didn't have to be that way."

In the second season of "I Am Cait", Caitlyn continues to explore the friction between her long-held Republican beliefs and her new role in the transgender community. She reverses her earlier positive stance on presidential hopeful Ted Cruz on the issue of transgender rights, saying, "[Republicans] are not my people if they're against this issue. I think he's just totally misinformed."

"I Am Cait" airs every Sundays at 9 P.M. on E!.
