It's been a while!

Joe Simpson threw on his biggest jacket and partied it up at Warwick in Hollywood last night, and he must have had a great time, because he was in high spirits when we caught him heading home.

Jessica Simpson's dad announced he was battling prostate cancer last year, but he seems to be on the mend.

"At this point, I am spending time with my family. They are my biggest support. The cancer continues to be monitored, and I am doing everything the doctors are telling me to do. I’m looking for a miracle," he told In Touch in October.

"Right now the outlook is great, but no matter what, I have to monitor this for the rest of my life. Once you have cancer, you have it — but I will get through this," he added.

We've missed him! Seeing him make a guest appearance on Vanderpump Rules was not enough!
