Nate Ruess and Charlotte Ronson are new parents!
Charlotte's mom, jewelry designer Ann Dexter-Jones, took to Instagram on Monday to share a collage of photos showing her bottle feeding the little guy -- whose face isn't shown in the pics.
"#iamsoinlove with my very first #newborn beautiful #grandchild," Ann wrote. "To the left of my photo that eludes you is an incredibly beautiful and adorable baby #takemyword."
Charlotte's brother, "Uptown Funk" artist Mark Ronson, shared a polaroid picture of himself also feeding Levon, which he captioned, "I love my nephew."
On Sunday, Charlotte's sister, English DJ Samantha Ronson, also shared a photo of her hanging with the new addition to the family. In the pic, a hoodie-wearing Samantha cradles the newborn in her arms as she smiled for the camera.
"Happy Birthday to you @nateruess! On your birthday I just want to say.... Thank you for the best gift ever..... my cafe du monde sweatshirt! Oh and my nephew is pretty awesome, too," she joked in the caption. "What a generous guy you are.... #happybirthdaynateruess."
Congrats to the happy couple!
