We consider ourselves celebrity gossip connoisseurs.

But we’ve never been able to figure out the couple known as “Vaughniston.” Are they together? Are they broken up? Should we refer to them as “Vinnifer” instead? Tough questions. Few answers.

Back in Bed? In fact, just when we though that the relationship was over, this nugget comes across our desk: On the afternoon of April 21, Vince Vaughn hopped into his blue Pontiac Firebird convertible and made a familiar journey to the Hollywood Hills home of Jennifer Aniston.

Apparently the former lovebirds had lots of catching up to do… in bed!

“Vince didn’t leave until 5 p.m. the next day,” an eyewitness - who must’ve been staring at her house for 24 hours straight - tells Us Magazine.

According to friends of each actor, though, it’s okay if these two got as nude as Kristine Lefebvre together. An Aniston friend says she can trust Vince, while a Vaughn source said:

“It’s no big deal if he stayed over. They are friends and can be friends with benefits.”

Shockingly, though, L.A.-based psychologist Ava Cadell says it’s difficult for people who have been in a sexual relationship to remain friends, “so the fact that they did remain friends really shows good character and stability.”

That’s some seriously expert analysis, doctor. Are you gonna tell us next that it’s difficult for Andy Baldwin to find true love on national television?

“It all depends on what their intentions are,” says Cadell, ignoring our mockery and talking about Vince and Jen. “It’s healthy, as long as they both want to do it and it feels good.”

Hear that, readers? Go sleep with your ex, as long as you each want to and orgasms result from the hook-ups. (Somewhere, Kevin Federline is totally calling Britney right now.)

Anyway, let’s take a look back at the ups and downs of Vaughniston’s romance

Epidermolysis Bullosa Medical Research Foundation

"The EB Medical Research Foundation was established in 1991 by Gary and Lynn Fechser Anderson at the request of Dr. Eugene A.

The Lili Claire Foundation

Lili died when she was five and a half months old after undergoing an eighteen-hour open-heart surgery to correct a severe heart condition associated with the disorder.

Friends of El Faro

"Mama Carmen and Papa Jorge, drew their circle in the sand and started this orphanage seven years ago, saying yes, to abused and abandoned children who were dropped off at their house, who would otherwise be living on the streets, or worse; and the children, they are our children, all, our children."

St. Jude Children's Research Hospital

"St. Jude is unlike any other pediatric treatment and research facility anywhere. Discoveries made here have completely changed how the world treats children with cancer and other catastrophic diseases. We are where some of today's most gifted researchers are able to do more science, more quickly. Where doctors across the world send their toughest cases and most vulnerable patients. Where no one pays for treatment beyond what is covered by insurance, and those without insurance are never asked to pay. We've built America's 3rd-largest health-care charity, with a model that keeps the costs down and the funds flowing, so the science never stops. All patients accepted for treatment at St. Jude are treated without regard to the family's ability to pay."

St. Jude was founded by Danny Thomas, the father of Marlo Thomas, who played Rachel's mom on Friends.
