Actress Hilarie Burton and her boyfriend Jeffrey Dean Morgan have reportedly been keeping a huge secret for the past few months.

Burton took a break from Hollywood recently and has been holding out on the fact that she and her boyfriend had a baby! The former “One Tree Hill” star went public with her relationship with Jeffrey in April 2009 at the premiere for her movie “The Losers” and managed to keep not only the birth of their new son but also her pregnancy under wraps …. up until now.

According to US Magazine, Burton wasn’t publicly photographed between May 6, 2009 and April 20, 2010, which is when she and Morgan went public with their romance at an L.A. film premiere.

Now back at work to film episodes of USA’s series White Collar in NYC, Burton told the Associated Press recently that she and Morgan are “really happy, and we’re a very good team. And we got very lucky that our family is what it is.”

But Burton still would not tell the AP the name of their son or his birth date. “I want to protect them like a mama wolf should,” she explained of her new family.

It’s the first child for Burton, but not Morgan: he learned in March 2009 that he had a 5-year-old son with actress Sherrie Ross.

Now that’s how you keep a secret!
