The name of Mick Jagger's new baby has been revealed and it's even more rock 'n roll than you could imagine.

The singer, 73, and his 29-year-old girlfriend, Melanie Hamrick, welcomed their son on Dec. 8 in New York, but failed to release many details of the birth.

On Friday, Dec. 16, Mick's daughter Elizabeth (who, by the way is 32 years old and older than his girlfriend) briefly shared a photo of her baby brother on Instagram before deleting the post.

"My beautiful baby brother Deveraux Octavian Basil Jagger," she captioned the photo of the little tyke before taking it down.

It's Mick's eighth child. His children now range in age from one-week-old in Deveraux's case to 46 years old, in the case of his eldest child Marsha Hunt. He is also a great grandfather.

"Melanie Hamrick and Mick Jagger's son was born today in New York and they are both delighted," a statement said at the time of the birth. "Mick was at the hospital for the arrival. Mother and baby are doing well and we request that the media respect their privacy at this time."

Reports out of the United Kingdom claim the child was named Basil after Mick's late father, who passed away in 2006.

The Mirror says that the name Deveraux is French and is thought to mean "riverbank," while Octavian is a Latin name meaning "born eighth," which is certainly fitting.

According to The Sun, the Rolling Stones frontman has mixed emotions about becoming a father again, considering his age.

"Family is extremely important to him, and he is unhappy at the thought that when he should be teaching his kid to play catch, he'll be 80 years old," the source said.

The Daily Mail reported that Mick and Melanie plan to co-parent the child, but don't plan on marrying. The duo already worked out a financial arrangement.

"Mick wanted to make sure that the deals and money aspects were in place before Christmas and the birth of their child," a source said. "Mick insists that he will be stand by Melanie throughout the child's first 18 years. After that they will make sure that the child's future is provided for too whether it be a career or seeking further education. This is a very amicable deal which has been agreed between a couple, who are not married, but are devoted to doing the right thing for the child."
