And baby makes six for the O'Donnells.
Chris O'Donnell and wife Caroline welcomed a baby boy Friday, the happy couple confirmed to Us Weekly. This is the couple's fourth child together.
"Mother and son are doing great," O'Donnell's rep, Leslie Sloane Zelnik, told the magazine.
The family lives in Los Angeles, where she is an elementary school teacher. Her expertise with kids must come in handy for the growing O'Donnell brood, which already included Lilly Ann, 6, Christopher Eugene, 5, and Charles McHugh, 2.
"He is a really great dad," Krista Allen, O'Donnell's costar on the now canceled Fox legal comedy Head Cases, told Us in September. "He has three fantastic kids and a beautiful, amazing wife. They are just this solid, great family, and Chris is just a doll."
Chris O'Donnell, 35, and the former Caroline Fentress, 33, met when the Batman and Robin star was still toiling in the halls of higher education at Boston College. In a romantic coincidence straight out of the movies, O'Donnell was roommates with Fentress' brother. After sweeping her bro's schoolmate off his feet, Fentress and O'Donnell tied the knot in 1997.
Although the actor's brush with the law ended when Head Cases got the axe, O'Donnell will next try his hand at medicine, with an eight-episode guest stint on the ABC hit Grey's Anatomy beginning Apr. 2. He will be back on the big screen in 2007 in the Matt Nix-directed black comedy Cock & Bull, costarring Sarah Polley.
