Rocker Jon Bon Jovi and his wife, Dorothea, have given birth to their fourth child, Romeo Jon, New York's Daily News reports.

The 9-lb. 7-oz. boy was born Monday and joins the couple's three other children, 10-year-old daughter Stephanie Rose, and sons Jesse James Louis, 9, and Jacob Hurley, almost 2, according to the paper.

Bon Jovi, the band, has been topping the charts since the late 1980s, with albums like "Slippery When Wet," "New Jersey" and 2002's "Bounce." Bon Jovi's role of father, however, is clearly something he enjoys. "You think you're in love when you're a kid and you meet your wife and get married, but you know you're in love after you have a child," he told PEOPLE in 2002.

Meanwhile, the singer also has exercised his thespian muscles in recent years, concentrating on acting gigs such as "Ally McBeal," "U-571" and "Pay It Forward." Bon Jovi reportedly is now at work on a low-budget comedy titled "The Trouble With Frank."
