George Clooney and Jen Aniston — TOGETHER … on a Private Jet

What happens in Switzerland, doesn”t stay in Switzerland … especially when George Clooney and Jennifer Aniston get on a private plane … TOGETHER!

It all went down at the Lugano Airport, where Clooney and his GF Stacy Keibler boarded a fancy private jet … followed by Jen and her BF Justin Theroux.

Pretty shocking … considering we haven”t seen Cloon and Aniston in the same place since Jen divorced George”s BFF Brad Pitt … back in 2005.

Since Clooney and Pitt are tight, it could be a sign Brad and Jen have buried the hatchet. On the other hand it may have nothing to do with that at all.
