Khloe Kardashian

E! NEWS -- Family comes first, as Khloé Kardashian and Bruce Jenner can attest.

Bruce Jenner
Last month, Bruce announced to Diane Sawyer—and 19 million viewers—that he is transitioning to life as a woman. The Olympic gold medalist discussed his family's varying reactions to the news, and at the time, he revealed that Khloé "had the toughest time with it because she's had a lot of losses in her life," citing her father Robert Kardashian Sr.'s death and husband Lamar Odom's "issues" as examples. Bruce knew that information might surprise some people, telling Sawyer, "You would think out of all of the kids, Khloé is the most fun, open-minded...and that's not the case with Khloé. She's very emotional."

Khloé tweeted her support after the special aired, and since then, it seems the reality star has begun to accept Bruce's transition.

(At this time, Bruce is choosing to not live publicly in the media as a woman and will be referred to with male pronouns until he specifies otherwise.)

In an exclusive sneak preview from E!'s two-part special, Keeping Up With the Kardashians: About Bruce, Khloé arrives at Bruce's house in Malibu bearing gifts. "I got you some pressies," she tells her stepfather.

"Are those from you?" Bruce asks, shocked by her show of support.

"Yeah!" Khloé says. "I don't know her taste yet, so I'm trying to figure that out."

"Well, to be honest with you, I don't now her taste either," Bruce, 65, admits. Visibly moved by her kind gesture, he asks, "But do you know how nice this is? Without even opening them, do you know how nice this is and how much I appreciate this?"

"Well, good," Khloé tells him. "You deserve it."

E!'s two-part About Bruce special will also include family home video footage.

Part One premieres Sunday at 9:00 p.m. Part Two follows Monday at 9:00 p.m.

In addition to the two-part special, an eight-episode documentary series showing Bruce's new life as a transgender woman will debut July 26 at 9 p.m. on E!
