Barbie and Ken have ironed out their differences, and after a seven-year separation, are back on again, with Mattel announcing a limited edition "She said yes!" gift set to celebrate their reconciliation.

While the romantic announcement was timed for Valentine's Day, more cynical observers might think it's a career ploy from the 50-something fashion doll: It coincides with the opening of Toy Fair, the industry's biggest annual event, now under in New York.

The El Segundo, Calif.-based toy marketer says Barbie updated her Facebook status to "In a relationship," officially ending the seven-year break. (Fans will recall she ditched him for an Australian surfer.) Ken has been Tweeting all month about his romantic gestures, the company says, "to prove that even though he is plastic, his love is real." The couple also merged their Facebook pages.

Ken even got a new look: The Wall Street Journal reports that the company's "Celebrating Ken" party at Christie's auction house included six new looks, like "Concert Date" and "Picnic Date." Models with really good hair and tuxedos greeted guests.
