Meet Bruce Willis’ Baby Daughter Mabel Ray, 1 Month!

My oh my, Mabel!

Bruce Willis became a fourth-time father last month when his wife Emma Heming gave birth to daughter Mabel Ray.

And first-time mom Heming introduced little Mabel to the Twitterverse on Thursday morning with a heartbreakingly cute photo of her husband, 57, cradling little Mabel.

"A beautiful day in Budapest with the loves of my life," the model-designer wrote beneath the photo, in which the Die Hard star kisses and snuggles a smiling Mabel, born April 1. "Daddy and Mabel cracking each other up." (On Wednesday, Heming joked that breastfeeding makes her feel like a superhero, tweeting: "I make milk. What's your superpower?")

It's the first child together for the vacationing couple, who wed in March 2009 in the Turks and Caicos Islands.

Mabel has three older half-sisters in Rumer, 23, Scout, 20, and Tallulah, 17, his kids with ex-wife Demi Moore.

48-year-old Moore made a stir on Twitter last week when she finally changed her handle — opting for "justdemi" instead of "MrsKutcher," an outdated nod to her soon-to-be-ex-husband Ashton Kutcher.
