The 35-year-old and Rozonda “Chilli” Thomas looked "super in love" at Warwick nightclub in Los Angeles on Wednesday, September 14.
The America’s Got Talent host was performing as a DJ at the club and was spotted being "super affectionate" towards the TLC singer.
"Nick and Chilli were all over each other. He was deejaying and any chance they could get they kissed and hugged and were super affectionate,” a source said to Page Six.
The father of two — who split from his ex-wife in 2015 — and the 45-year-old made no attempt to conceal their new romance.
"He was so focused on her, it was obvious that they were together. She stood right by his side almost the entire time and he couldn't take his eyes off of her,” the source continued.
“They looked super in love and left the venue together around 1:30 a.m. They are definitely serious and very happy together at the moment!"
This isn’t the first time the two have hung out — the actor met up with the “Waterfalls” singer in July during a show in Rochester, New York and they spent Fourth of July together.
Though the Drumline star recently said he will never get married again, he seems happy taking things slow with his new lady.
