Ashlee Simpson and Evan Ross are keeping the trend of unique baby names alive. The Hollywood couple revealed over the weekend that they have named their newborn daughter Jagger Snow Ross.

Simpson, 30, gave birth to her second child on Thursday, her first with new husband Evan Ross, 26. While the couple has yet to release photos of their new addition, they did take to Instagram over the weekend to share her name. Both Simpson and Ross posted the same announcement on their separate accounts:

“We are overjoyed about the birth of our precious baby girl, Jagger Snow Ross, July 30 2015 – Ashlee & Evan.”

Jagger Snow is definitely an unusual name, and the parents have not given any hint to the meaning of it. Of English origin, Jagger is generally associated with singer Mick Jagger of The Rolling Stones. Meanwhile, the baby’s middle name, Snow, could be connected to late bluesy singer Phoebe Snow, or possibly even the beloved Disney princess, Snow White.

Whatever the meaning behind Jagger Snow may be, the newborn joins big brother Bronx Mowgli Wentz, 6, who Simpson shares with ex-husband Pete Wentz of the band Fall Out Boy. She’s also got a couple of famous cousins to spend time with – Jessica Simpson and Eric Johnson’s two children, Maxwell Drew and Ace Knute.
