Awkward! Earlier this week, Keith Richards slammed his Rolling Stones bandmate Mick Jagger for welcoming his eighth baby at age 73 — and now the musician is apologizing for his “out of line” remarks. “I deeply regret the comments I made about Mick in the [Wall Street Journal] which were completely out of line. I have of course apologized to him in person,” Keith wrote via Twitter on Wednesday, Feb. 28.

Earlier on Wednesday, Keith, 74, suggested Mick should get a vasectomy after recently becoming a dad for the eighth time. “It’s time for the snip — you can’t be a father at that age. Those poor kids!” he told the WSJ. Mick, now 74, welcomed son Deveraux Octavian Basil Jagger with his 31-year-old ballet dancer girlfriend, Melanie Hamrick, in December 2016.

Mick is also a father to seven older children with four other women: Karis Jagger, 47, Jade Jagger, 46, Elizabeth Jagger, 33, James Jagger, 32, Georgia May Jagger, 26, Gabriel Jagger, 20, and Lucas Jagger, 18. The rocker is additionally a grandfather-of-five and became a great-grandfather in 2014. Keith also has four children — Marlon Richard, 48, Angela Richards, 45, Theodora Richards, 32, and Alexandra Richards, 31 — and five grandchildren. One of Keith’s sons, Tara Richards, sadly died as an infant from SIDS in 1976.

Though Mick and Keith have been Rolling Stones bandmates for more than 50 years, the two have always had a contentious relationship. In his 2010 memoir, Life, Keith called Mick “unbearable.” He later said, “Mick and I would have spats anyway, no matter what I said in the book, and I left a lot out. [But] Mick and I live off of this fire between us.” In another interview, Keith said his friendship with Mick has always been “up and downhill,” but there “ain’t a front-man like Jagger.” He added, “Don’t matter how many bones you want to pick out of him, he’s amazing to work with.” Hopefully, Mick will accept Keith’s latest apology!
