Ed Westwick is feeling the XOXO.

The Gossip Girl alum and his wife Amy Jackson welcomed their first child together, they announced on March 24.

“Welcome to the world, baby boy,” the couple wrote in a joint Instagram post, sharing black-and-white photos of their son. “Oscar Alexander Westwick.” 

The newborn joins 5-year-old Andreas, who Amy shares with ex George Panayiotou.

The couple’s family’s newest addition comes six months after Ed, 37, and Amy, 33, tied the knot during a lavish wedding ceremony at the Castello di Rocca Cilenta, a five-star hotel located inside a walled-off castle near the Amalfi Coast in Italy.

“The journey has just begun,” the two wrote on Instagram shortly after the August nuptials, adding in another post, “With the sun setting behind us, surrounded by our dearest friends and family, we exchanged our vows in a moment we’ll cherish forever,” the two wrote on Instagram at the time.”
