Robbie Williams has hit out at Jessie J, claiming that he expects her pop career to be short lived, giving her 18 months at best.
When speaking to a Dutch TV show, the 38-year-old claimed her music career would be finished in a matter of "18 months".
"She's not gonna last for very long, though, is she?" he is reported as saying on the show. "She's great, Jessie. I give her 18 months."
According to The Sun, Williams has also criticised the 'Price Tag' singer for her role as a judge on TV talent show 'The Voice'.
He explained how he has become apathetic towards the constant 'sob stories' of the contestants on the show.
"I don't watch it, sometimes it's very difficult to go on the 'emotional journey' with the contestants'.
"I'm exhausted with how many times I'm to go on the emotional journey with this person who had a hard luck story and then da, da, da, da, blah, blah."

The 'Angels' singer also joked that he would be well capable of being a judge on a TV talent show, but feels no need to do so.
He added: ""I'm sure I'd be a good judge", before adding: "But no, I've got a career. So..."
It remains to be seen how his comments will be received by Williams' Take That bandmate Gary Barlow, who is currently taking part in his second series an X factor judge.
Just last month Williams and Barlow appeared together on the show to host a contestant master class, and Williams performed live on the show.
It has been a successful couple of weeks for Williams. Last week his new single 'Candy' shot straight to the top of the chart. Yesterday his new LP 'Take the Crown' also topped the album chart.
The singer has recently become involved in a war of words with Radio 1 breakfast show presenter, Nick Grimshaw.
