Although she has never had full sex on a plane, the reality TV star has confessed she once performed an erotic act on her husband Hank Baskett on a Southwest Airlines flight which she believes qualifies her as a member of an exclusive group, just not the mile high club.

In a series of Twitter posts, made while using in-flight WiFi, she revealed: "I just asked @TheHankBaskett if he wanted to sext while I'm on the plane. I love wifi ... I'm still not in the mile high club ... I actually gave Hank a BJ on southwest. Does that count as mile high club?!?! Hahahahahahahhaahahaa (sic)"

Kendra's outrageous revelation led to some of her followers to criticise her for over-sharing when she's a mother-of-two.

However, the 30-year-old blonde bombshell - who has six-year-old son Hank Jr. and 22-month-old daughter Alijah with her spouse - defended her decision to share her sexy story.

She tweeted: "I'm a mother because of sex. Remember that."

Kendra didn't reveal who she was flying with or where she was travelling to but she was so excited she couldn't sleep for the whole 14-hour trip.

She tweeted: "Stayed up the whole 14 hour flight. Wish me luck today."
