Khloe filed for divorce from the basketball star on Friday (13.12.13) and his daughter Destiny - one of two children he has with ex-partner Liza Morales - doesn't want them to get back together.
Writing on her Ask.fm page, she said: ''No one thought they were going to last, so honestly, who [cares].''
Asked if she thinks they will reconcile, she responded: ''I don't want it to happen anyways. I have him all to myself now!''
When another person wrote to Destiny, 15, advising her mother to get a lawyer to ensure Lamar's fortune is protected during the divorce, she replied: ''It's called a PRENUP and [thank God] for it.''
When asked if she would still ''be cool with Khloe'' Destiny was quite clear in her reply, simply writing: ''hahahahahahahahahahahhahahahahahhahahahahahhahahaa.''
Lamar and Khloe got married in 2009 just one month after they had met and she had enjoyed a healthy relationship with Destiny and her younger brother, Lamar Jr., 11 throughout their marriage.
Khloe officially split from Lamar in September after allegations of him abusing drugs and being unfaithful surfaced.
He is said to be ''deeply saddened'' by the divorce filing, but a source said
''He knew it was coming and it was only a matter of time.''
