Rock on! Ashlee Simpson and Evan Ross are in "L.O.V.E." with their newborn, and they’re finally sharing the little girl's name.

The proud parents announced the baby's name via their Instagrams on Friday, after welcoming their daughter into the world on July 30.

"We are overjoyed about the birth of our precious baby girl, Jagger Snow Ross," they wrote, signing the note "Ashlee & Evan."

Both Simpson, 30, and Ross, 26, shared the same caption, tagging each other and writing, "I love you #JaggerSnowRoss we love you."

How cute is that?

This is the first child for the couple, who were married last August, and the second for Simpson.

The "Pieces of Me" singer has a 6-year-old son with her ex-husband, Fall Out Boy bassist Pete Wentz. Seeing as their boy's name is Bronx Mowgli, Simpson's new daughter clearly needed an equally unique name. Wentz also welcomed a second child, son Saint Lazslo, in August 2014 with girlfriend Meagan Camper. Hollywood names abound for these musical families!

It's pretty safe to say that the unique moniker for the newest member of the Simpson-Ross clan pays homage to that famous Rolling Stone, Mick. Jagger has an English origin and is usually bestowed upon boys, though actress Soleil Moon Frye also gave her now 7-year-old daughter the same moniker when she was born in 2008.

Congratulations to the happy parents!
