Kendra Wilkinson Shares NSFW 'Boobs' Selfie, Awkwardly Reunites With Former 'Girls Next Door' Pal Bridget Marq

Kendra Wilkinson and Bridget Marquardt talk it out.

Kendra Wilkinson is in a sharing mood.

The 30-year-old former Playboy model took to Instagram on Thursday to show off her assets, sharing a jaw-dropping bikini pic with her 1.8 million followers.

"Boobs," she captioned the cleavage-baring selfie.

Meanwhile, the mother-of-two is also baring herself emotionally on this season of Kendra on Top. In a clip from Friday's episode, she reunites with her Girls Next Door co-star, Bridget Marquardt, who confronts Wilkinson about her past comments that the two never had a real friendship.

"When I saw things like, 'Well, we were never friends,' and, 'She's not appreciative,' and things like that, I'm thinking all the things that we did together -- like, all the time at the mansion, from all the traveling around the world, the parties, and getting ready in my room ... " an emotional Marquardt, 42, tells Wilkinson. "We weren't always best friends, but we definitely had each other's back, and I definitely consider you a friend."

"To say that we were never friends, kind of, like, illegitimizes all that time that we had together, and all the things that we did," she adds.

An apologetic Wilkinson surprisingly admits she handled their friendship in the wrong way.

"You know, I did have -- as we all did -- probably, like, a hard time transitioning into, like, a world outside the mansion," she explains. "When I was saying those things, it was more about, like, trying to distance myself from the mansion as much as I could, which was the wrong thing to do."

"I loved the time that we had together," she stresses.

Meanwhile, Wilkinson has yet to mend fences with her other Girls Next Door co-star, Holly Madison. In Madison's 2015 tell-all memoir, Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny, she accuses Playboy founder and ex-boyfriend, 90-year-old Hugh Hefner, of emotional abuse and giving her "thigh-opening drugs." Madison, 36, stated that things got so bad that she contemplated suicide, while Hefner has since denied all these accusations.

"I just never saw hope and friendship with her," Wilkinson now says about Madison when Marquardt brings her up. "There was never a moment where I can say she felt real to me. Do we owe it to ourselves to hear each other out? For sure. But if that never happens, then that's the way it's gonna be I guess."

In September, Wilkinson slammed Madison's claims against Hefner in an episode of Kendra on Top.

"What Holly is saying is extremely false," Wilkinson said. "I'm like, 'Where did this s**t come from?' ... Someone needs to have a voice against this. Hef won't do it. He's too nice of a guy. It's just weird how someone can get away with such a thing."
