Mary-Louise Parker plays a housewife who starts selling drugs after her husband (Jeffrey Dean Morgan) dies. But in real life, Parker and Morgan's romance is very much alive.
"It's going great!" Parker, 43, says of Morgan, 40, who also died on Grey's Anatomy
(after romancing Katherine Heigl's character) and Supernatural
(after making a deal with a demon to save his son).
And don't believe any gossip-column reports of trouble in paradise: "The New York Post
said we were fighting at Nobu, but I'm certainly not dumb enough to fight at a [high-profile] restaurant like Nobu."
In fact, she recently spent Valentine's Day with Morgan ("We had a nice dinner") and her other favorite guy: her son William, 3, with actor Billy Crudup. "He made Valentines for everyone," she says.
Parker, who stars in Oxygen's The Robber Bride
(March 3, 10 and 11), starts filming the new season of Weeds
in April. Is it hard being a working single mom? "No, because I spend a lot of time not working," she says.
She even has time to take William to his class: At a time when most toddlers are learning to tumble, he's taking French lessons. "He speaks a little," Parker says. "He can count to seven and say, 'May I please have two cookies?' "
