Last October, Kurt Cobain's daughter Frances Bean married Tony Hawk's oldest son Riley. Cute! In the time since then, they did a really good job of keeping Frances' pregnancy a secret. Over the weekend, the couple announced that on Sept. 17, they welcomed their first child together, a boy named Ronin Walker Cobain Hawk.
Frances and Riley shared the news of their parenthood via a series of black-and-white Instagram photos. The comments were flooded with congratulations from the likes of Frances' godfather Michael Stipe, Kim Gordon, Christina Ricci, and of course, grandpa Tony, who proclaimed: "My favorite grandson!" (This is his only grandson.)
Congrats to the new parents and to Courtney Love becoming a grandmother! See the photos below.
