Meet William Luca Costa-Marsden!
X-Men star James Marsden stepped out for an afternoon stroll with his 5-month-old son in Los Angeles, Calif. on Sunday (May 26). This marks the first time we’ve seen baby William, whom is James’ son with ex-girlfriend Rose Costa.
The 30 Rock star, 39, briefly dated Costa after his split from wife Lisa Linde in 2011.
Marsden and Linde are parents to daughter Mary James, 7, and son Jack Holden, 11.
