According to the site, Kardashian hadn't been photographed publicly since the end of March.

Earlier this week, Kardashian's older sister, Kim, revealed he was shocked by his step-father's debut as Caitlyn.

"It was so funny because all the girls, we knew that Caitlyn was shooting this but my brother had no idea," Kim revealed during the CDFA Fashion Awards, according to a Perez Hilton report on Tuesday. "So I sent it on a mass text to everyone and my brother was on it and he goes, 'Kim, why are you sending me this? Who is this woman? And why do I care?' And I was like, 'Rob, that's Bruce! That's Caitlyn!' And he was like, 'Oh my god, she's beautiful!' And then he called her and they had a lovefest and it was so cute. But the moment was so funny."
