Model and actress Devon Aoki ('2 Fast 2 Furious') and her fiance, James Bailey, welcomed a son into the world last week, the couple's first child.

The news spread thanks to the doting dad, who posted pics from the hospital on Twitter to show off their beautiful newborn boy. He also expressed his joy to followers.

"Celebrating the birth of our son, and Devon and my anniversary yesterday is more than I could ever ask for," the financier tweeted. "Our family keeps growing."

He later added, "Exhausted 38 hours later but seeing him open his eyes and follow Devon and I and respond to music is worth every hardship."

The couple reportedly became engaged last summer, and in January, a rep for Aoki confirmed she was pregnant, adding, "Devon and James are extremely happy."
