"Excited to see my baby girl next week!!!!!!!!!!" he wrote on Twitter.
Until now, the MTV star has claimed the baby's mother, Amanda Markert, won't allow him unsupervised visitation rights.
Sources tell Radar that Pauly filed for full custody weeks before the story went public.
As Radar previously reported, Pauly D revealed he and Markert had not been in a relationship, beyond a hook-up in Las Vegas in 2012.
“He wasn’t exactly planning for it to happen this way,” a source said, ”but God works in mysterious ways.”
The 33-year-old spinner revealed he is ready to step up and take responsibility.
"Sometimes in life things aren't planned and they may even scare you at first, but they end up being a blessing, that is how I feel about having a daughter," he said in a statement to Radar. "I'm looking forward to being a parent to her."
