Perez Hilton slammed the reality TV star and insisted he doesn't expect her marriage to Kanye West – with who she has 14-month-old daughter North – will last, though he does expect them to have another child.
He told Closer magazine: 'Her fame is out of control now she's with Kanye. Kim's desperate for another baby and they'll probably last until she gets that.
'She's smart enough to know that you need to have at least two children to get as much money as possible!
'As we know, Hollywood couples never last the course – there are too many egos involved!'
The acid-tongued gossip blogger explained his pessimism about the longevity of Kim's fame, suggesting that people are losing interest in the 33-year-old beauty and shifting their attention to her younger half-sisters, Kendall and Kylie Jenner.
He added: 'Kendall and Kylie are the future. People are interested in their edgy style and crazy antics.
'Kim, Kourtney and Khloe are simmering with jealousy! The whole thing's bound to end in a massive bitch fight!'
