But of course the musician isn't the first celebrity to draw inspiration from nature when choosing a name for her child. Here's a look at a few other earthy baby names celebrities have come up with:
Many celebrities are fans of the herbal middle name Pink gave her daughter. Sylvester Stallone's son Sage actually appeared with his dad in "Rocky V," but the name is more popular for female celebrity babies -- Toni Collette's daughter Sage Florence was born in 2008, while CNN Newsroom anchor Kyra Phillips and her fiance, FOX News correspondent John Roberts, had a daughter named Sage Ann on March 15 of this year. She was joined by twin brother Kellan Clay, who also has a somewhat earthy name.
Rocker Keith Richards of the Rolling Stones is about to become a grandpa again -- his 38-year-old daughter Dandelion is eight months pregnant (at least Richards didn't dub his daughter Mary Jane after a different kind of weed!).
Jennifer Garner and Ben Affleck are fans of this flower, naming their daughter after the sweet-smelling blossom in 2005. Last February singer Christina Milian and The-Dream also welcomed a daughter named Violet Madison, and months later Claudia Schiffer named her baby girl Cosima Violet."
Why people do this to their kids is a mystery - and some of these names are not terrible! But some others... YIKES.
"Worst Baby Names

Part twoA cousin of a friend of mine named her daughter Tyranny. My uncle (a police officer) locked up a woman named Sh*thead, only without the asterisk- pronounced Shi-TAYd.
— Anonymous, Baltimore, MIAbout 20-25 years ago I knew a man who gave his son the name "Alias." His girlfriend, the mother of the child, apparently thought the name was pretty cool so there is a man now walking this earth named "Alias." This must raise some eyebrows when he fills out a job application or experiences a minor traffic stop. I don't even want to think about an encounter with Homeland Security.
— Anonymous , Wilbraham, MABrock Lee. I'm not sure what they were thinking! Or even if they thought about it until after the fact.
— Lisa Stricker, Clarksburg, WVPajama (pronounced pay-jeh-meh). [The mother] mentioned she was looking through a Sears catalog when she was pregnant and the name jumped out at her and she knew right then and there, this was to be her daughter's name. I asked her how to spell “Pay-jeh-meh” and she replied P-A-J-A-M-A. . I thought to myself, oh no! Her poor daughter is named after Sears catalog sleepwear.

— Teresa Walls, Ransomville, NYWhen I worked in retail, a young couple came in and were discussing their baby's name with an associate of mine.

Seriously.

— Sandra Trisdale, San Diego, CAMy Coworker was pregnant and I asked her if she had a name picked out yet. She said no, but she wanted to stay away from weird names, like the one her sister had given her niece. The name? Felanie. Like Melanie, but with an F. If there's such thing as cursing your child, I think that may take the cake.
