Rockstar, Steven Tyler, has become a grandpa for the fourth time.
His daughter, Mia Tyler, and her boyfriend, Dan Halen, have welcomed their first child together.
The baby boy named Axton was born on Wednesday.
The proud new mom shared the first photos of her son via Instagram, with the caption, "The love of my life has finally arrived and I am now complete. No words can explain how I am feeling. Just pure unfiltered love. My son, Axton born May 10th at 5:45 am."
The 69-year-old Aerosmith frontman met Axton moments after he arrived. Mia's older sister, actress Liv Tyler, has two sons Milo and Sailor, and a 10-month-old daughter named Lula.
