Pauly D is a daddy! The "Jersey Shore" cast member has a 5-month-old daughter named Amabella, TMZ reports. The girl's mother has not been revealed but the two reportedly hooked up in Las Vegas in the Fall of 2012. According to the celebrity website, Pauly has already taken a DNA test and the baby definitely belongs to him.

Not much is known about the child's mother except she is 25, was born in New Jersey and had a brief fling with the famous DJ. Amabella, born on May 15, lives with the mom.

"I'm proud I'm a father. I am excited to embark on this new part of my life," Pauly told TMZ.

According to E! News, Pauly, 33, and the mystery woman "didn't have a previous relationship" but he is reportedly interested in developing something romantic with her.

"[He] wasn't exactly planning for it to happen this way," a source said. "But God works in mysterious ways."

The source also said that the DJ is ready to take on the responsibility of being a father. So far Jennifer "JWoww" Farley is the only cast member who has spoken out about the news.

"Holy s**t I just heard!" Jennifer "JWoww" Farley told E! News. "I'm so f**king happy for him I just texted him. Crying! He's going to be the best dad ever!"

Pauly now joins cast mate Nicole "Snooki" Polizzi as parents. The pint-size reality star has a son, named Lorenzo, with her fiancé Jionni LaValle. Baby Lorenzo celebrated his first birthday in September.

Recently JWoww dished about baby Lorenzo and the new season of their show "Snooki and JWoww" to Hollywire.

"It was so much fun, we lived a mile apart, Lorenzo's walking, Nicole's able to do a lot more because she's not pregnant and I feel like we just took on every day like it was a nice adventure," she said. "It ended up, to me, being one of the best seasons ever. It was just a lot of fun."
