Joan and Melissa Rivers are back for Season 4 of WE tv’s Joan & Melissa: Joan Knows Best? and this time around, Joan’s having a “senior life crisis.”

The Fashion Police host phoned in to On Air with Ryan Seacrest and joked about it, saying: “We better hurry because I’ve been a senior for so damn long!”

This season, we’ll see Melissa desperately try to keep her mother under control while balancing her own chaotic life and 13-year-old son, Edgar Cooper Endicott.

We’ll also see Joan turn 80-years-old, which inspires her to pledge to live her life to the fullest and nothing is off limits, including making a sex tape!

As for being a grandmother to Melissa’s teen son, the comedian shares: “The girls are starting to call … Melissa [answers the phone] and Melissa reads his emails. She’s a good mother.”

And she needs to be because Joan adds: “13-year-old girls send him pictures [saying] ‘Do you want to see my booty?’”

As for Joan’s backside, of course she had to joke. “My booty you can see. It drops so low everybody sees it.”

Catch the Season 4 premiere of Joan & Melissa: Joan Knows Best? on WE tv on Saturday, March 29 at 10 p.m.

But before then, Joan will be on QVC on Sunday, March 16, to promote her Joan Rivers Classics Collection. Find out more here!
