Bruce Willis has a brand-new special lady in his life.

The 57-year-old actor's second wife, Emma Heming, gave birth to a daughter, Mabel Ray Willis, on Sunday, their rep tells Us Weekly in a statement.

Little Mabel Ray weighed in at 9 pounds, 1 ounce, and both baby and her model-designer mom, 35, are "healthy and doing beautifully," the rep says. This is the first child for the couple, who tied the knot in 2009. The rep added that Willis and Heming are "overjoyed" by the arrival.

It's the fourth daughter for Willis, who has three girls with ex-wife Demi Moore: Rumer, 23, Scout, 20, and Tallulah, 17.

Die Hard star Willis initially wasn't sure about becoming a dad again. A few months after their March 2009 wedding in the Turks and Caicos islands, the actor joked to Us Weekly: "It's been suggested we begin breeding immediately. [But we're taking it] just a day at a time. Really slowly."

His famous ex Moore, 48, whom he divorced in 2000, has kept an extremely low profile since her breakdown and rehab stay earlier this year. She and second husband Ashton Kutcher announced their split in November of last year.
