David Duchovny and his wife Tea Leoni separated today ... TMZ has learned.



Sources close to the couple tell us ... although David and Tea are taking time apart, they have not decided if they will file for divorce.

David and Tea were married back in 1997 -- and briefly separated in 2008.

The couple has 2 children together -- a 12-year-old daughter and a 9-year-old son.

... to his arms.




David Duchovny and his farmer's tan enjoyed a sex rehab-free Father's Day with reconciled wife Téa Leoni and their kids on the beach in Malibu.

The only Father's Day gift David needs ... a tan for his ripped pasty abs.

Weeks before her hubby David Duchovny checked into sex addiction rehab and two months before revealing they were already separated, Téa Leoni enjoyed some VIP treatment from rumored boyfriend Billy Bob Thornton.

On August 4th, Téa was on hand for Billy Bob's 53rd birthday (left) to watch him record a song at Sun Studio in Memphis. Two weeks later, the 42-year-old mother of two enjoyed a beer and a cig (right) at Billy's show with his band, The Boxmasters, in NYC.

Looks like Billy Bob still has a lot in common with his ex-wife Angelina Jolie and Brad Pitt -- he met Téa while working on a movie too. If John Mayer doesn't work out, maybe Aniston can date Duchovny.

David Duchovny and Tea Leoni announced they've been separated for months -- so why the hell did David just spend time in sex rehab?

All D.D.'s newfound freedom must have been too much for him to handle.

David Duchovny just got out of rehab for a sex addiction -- so we had to know, is his wife, Tea Leoni, gonna stick him in her ex-file?

Finally, someone over 40 who doesn't have a plastic surgeon on speed dial.

Thanks Tea Leoni, for keeping it real.

They're scratching it, pulling it and picking at it. And nothing is more stimulating than watching a star diggin' in!
