Ross, 26, gave birth to the baby boy, named Lars Gerard Gibson, on Friday, Jan. 20, and the couple is “over the moon.” Lars weighed in at 5 lbs., 5oz.

“They’re thrilled and Lars is adorable,” a source tells People. “Their family is all around them and Mel is over the moon. They’re home and everybody is healthy and happy!”

The couple announced the pregnancy last September, saying they were “so excited” to start a family together. “Mel loves being a dad and he and Rose can’t wait to be parents together,” told a source. “The last two years have been some of his happiest years he’s ever had.”

This is the first baby for the former pro equestrian and writer Ross. Gibson, on the other hand, had seven kids with his first wife Robyn Moore, including just one daughter, Hannah, 36, and six sons, Edward and Christian, 34, William, 31, Louis, 28, Milo, 26, and Thomas, 17. Gibson and Moore split in 2006. He also shares a 7-year-old daughter, Lucia, with ex Oksana Grigorieva.

Gibson’s film Hacksaw Ridge also earned six Academy Awards nominations this morning, including Best Picture and Best Director for Gibson. This is his first Oscar nom since 1996’s Braveheart.
