Frances Bean Cobain has secretly married her boyfriend of five years, Isaiah Silva. The daughter of Kurt Cobain and Courtney Love invited only a small circle of her close friends and excluded her mother. Frances reportedly only called Courtney afterwards to break the news.

"Courtney loves Isaiah, but was devastated to learn that Frances had gotten married without her knowing," a source tells E! News. "Courtney really likes Isaiah and is very happy for Frances. Courtney is sad she wasn't at the wedding."

The insider adds, "Frances called her after but understands why she did it. Frances needs a man in her life and has always craved stability. She's found it in Isaiah. This has not caused a rift between mom and daughter. Courtney was sad, but she's cool and Isaiah is a great son-in-law."

More than two decades ago, Courtney Love and Kurt Cobain also tied the knot in a small ceremony reportedly with only eight guests present. The Nirvana frontman committed suicide in 1994 two years after the wedding. Frances was only two years old back then.

Frances and her mother had a strained relationship in the past, but they have since mended it. On her 23rd birthday last month, Courtney sent her daughter a heartwarming note, "Happy birthday my sweetest baby girl, I'm so proud of you @alka_seltzer666," to which Frances replied, "Thanks for letting me utilize your human form to act as my alien incubation pod for 9 months. Love you mum XX."
