Uncle Ronnie loves Meilani! Jenni "JWoww" Farley's former Jersey Shore costar Ronnie Ortiz-Magro shared a sweet moment with her newborn baby daughter, Meilani Alexandra Mathews, on Tuesday, Aug. 19, the same day he revealed his split from Sammi "Sweetheart" Giancola.

Dressed in a pink-checkered shirt, a yellow tie, and a charcoal suit, Magro stopped by JWoww's home to spend time with her 5-week-old little girl prior to the New York premiere of Jersey Shore Massacre. He shared a photo of himself cradling Meilani via Instagram, writing, "#Family #LoveThem @rogermathewsnj #Heading to the @jerseyshoremassacre to support @jennijwowwmtv #RealMenWearPink #Meilani"

Farley's fiance, Roger Mathews, retweeted the photo on Aug. 20, adding his own funny caption. "Hi uNkle RoNnie," it read. "I'm still cuter than you even with my poop diaper. Smell better too."

As previously reported, Magro, 28, split from longtime love Giancola, 27, about two months ago. Speaking with Us Weekly at the Jersey Shore Massacre premiere, he explained that they "grew [their] separate ways" but are still close.

"She's still a great person. I love her as a person and I care about her, but we went our separate ways. That's it," the MTV star told Us. "At the end of the day, we went through a lot of stuff together. We have a lot of history, so I keep her close." 

He added, too, that he's "sticking to being an uncle" to Snooki and JWoww's kids, Lorenzo and Meilani, soon to be joined by Snooki's second child with fiance Jionni LaValle. Of Meilani, Magro gushed, "She's beautiful. She's like, 'I need attention! Look at me, look at me!'"
