We've know these two have had a strained relationship for ages -- but this newest one takes the (wedding) cake!

Over the weekend, news broke that Kurt Cobain and Courtney Love's daughter Frances Bean Cobain secretly got married to her longtime boyfriend Isiah Silva, whom she has been engaged to since 2011.

The Mirror UK, reported that the couple were married in a small ceremony that was only attended by a "close circle of friends." Apparently, that "close circle of friends" of 15 friends, did not include her famous mom, Courtney. The publication is also claiming that the Hole singer only found out about the nuptials after the fact.

E! News reported that the rocker didn't know and was extremely upset that she wasn't invited. A source told the site, "Courtney loves Isaiah, but was devastated to learn that Frances had gotten married without her knowing."

It looks like Court's "devastation" turned to embarrassment and then anger because instead of keeping her mouth shut, she went on the offensive, saying that she's the one who skipped the wedding (not that her daughter didn't invite her) basically because she was busy banging a boy toy.

The 51-year-old alluded the slight on Instagram on Saturday, when she posted a snap, getting snuggly with a very hot, very young man. Along with the caption, Courtney wrote, "If you think I'm sorry for being a no-show at any important events this week, think again. I was with @jamesnorley ❤ #candyface #worthflakingonanythingfor #heaven #worthit #slay #bae #cancelallmyappointments #donthate #stud #jealousmuch ? 😇😈 Bwahaa xc."

Get real and grow up, Courtney. Trying to pretend you snubbed your daughter instead of the other way around is lower than low! We get that you two have a strained relationship, but we think that's most likely that Frances has wanted to distance herself from having a trainwreck of a mother.

It's too bad that Courtney couldn't get over her hurt feelings and put the feeling of her daughter over hers -- but we think this is probably why the two aren't so close as it is.

Congrats Frances Bean -- we're happy for you, even if Mommy Dearest isn't!
