Newly-divorced Brad Pitt is gracing headlines all over the world for his relationship with Angelina Jolie, but now Brad's ex, Jennifer Aniston, is creating some headlines of her own.

Photos recently surfaced of Aniston and Vince Vaughn hanging out and greeting young fans in Vaughn's hometown of Lake Forest, Illinois. Perhaps the pictures are a sign the co-stars are now officially a couple?

According to Us Weekly's Senior Editor Caroline Schaeffer, that's exactly what it means!

"Jennifer Aniston and Vince Vaughn are definitely more than friends," Schaeffer insisted. "They spent an entire weekend together in Chicago, and then he brought her home to meet his mother!"

Read all about Aniston's visit with Mom in the new issue of Us Weekly, on newsstands Friday.

Another recent Us Weekly headline screamed, "Jessica and Nick: Apart Again!" But just this weekend, Lachey told our Carlos Diaz that as far as his marriage is concerned, "Everything is perfect."

But Us Weekly is sticking by its story. "They say they're still together," Schaefer said. "They say they're a couple, but they're not spending any time together."

So why insist they're still together? Us Weekly has a theory.

"The final season of their MTV ‘Newlyweds' show is coming out on DVD in December," Schaefer said. "If they're going to promote that, they really should be a couple."

Meanwhile, forget Oprah, it seems "The Ellen DeGeneres Show" is the place where all the celebrities are spilling news about their love lives. Matthew McConaughey denied being engaged to girlfriend Penélope Cruz on DeGeneres' show, and Charlize Theron threatened to pull a Tom Cruise.

"I'm like this far away from jumping on the couch like Tom Cruise," Theron told Ellen. "But I'm not going to do that."

Tune in Wednesday to see Charlize jumping for joy on Ellen's show.
