"Our little man arrived! Jack Oscar Statham - 8.8lbs on Saturday June 24th. 👼🏼❤️" Rosie wrote on social media.
Now, Jack has made his second public appearance and first in a photo with his stunning supermodel mother.
Rosie took to Instagram earlier today, to share a photo of herself and Jack boarding a plane to jet off someplace for Christmas.
"Happy Holidays" she simply captioned the snap.
We can't get enough of this wintry, cozy snap.
Rosie isn't the only British star to share a new family photo ahead of the holidays, with the Royal Family releasing their annual Christmas portrait just this morning. See their beautiful photo (and exciting news about Princess Charlotte) here.
