Frances Bean Cobain has reportedly filed for divorce from husband Isaiah Silva after less than six months of marriage.

The 23-year-old daughter of Kurt Cobain and Courtney Love secretly tied the knot with musician Isaiah Silva, 31, in September (15), but according to TMZ.com, the couple has called it quits.

In legal documents obtained by the website, Frances indicates she is open to paying her estranged husband spousal support, however the fortune left by her dad's estate is completely off limits. The late Nirvana rocker's riches are reportedly valued at $450 million .

Frances and Isaiah dated for nearly five years before exchanging vows last autumn (15), and the ceremony was so top secret that the bride didn't even invite her mom. The Hole singer only found out about the nuptials after they had happened.

One insider told British newspaper The Mirror, "She only invited a close circle of friends to the party, and then phoned her mom afterward to tell her the good news.

"Courtney is sad she wasn't there but she totally understands that Frances is her own person and she’s happy to let her do her own thing. Plus, Isaiah is a really nice guy."

The split news comes two days after the mother-and-daughter team made a rare appearance together on Monday (21Mar16), when they attended the Liberatum event, celebrating Women In Creativity, at London's St Martin's Lane. Courtney was interviewed as the guest of honor.

Though their relationship has been tumultuous over the years, it's rumored mother and daughter reconciled last month (Feb16), after Courtney tweeted a picture of her daughter supporting her performance at a Los Angeles party.

"I'm so blessed to be the mother of the world's most incredible daughter.” she wrote.
