The X Factor judge Kelly Rowland has allegedly left her acts "in the lurch" and flown to the US rather than staying in the UK to mentor her acts.
The former Destiny's Child star has reportedly fallen out with fellow judges Tulisa Contostavlos and Louis Walsh after they objected to [uuid=7fbae74f-2fc8-4cd5-8edf-d8ce702181fc]receiving unsolicited advice from her[/uuid] on how to mentor their acts on the show.
Kelly has also apparently been left fuming after Walsh branded her act Misha Bryan a [uuid=20e48b02-912c-49d7-b825-000e2d6eeee3]'bully[/uuid]', and now XF bosses are concerned she may not return for the series' forth live show this coming Saturday (Oct 29).
'As the contest heats up, she's left the girls in the lurch all week,' a source told the Sun. 'It's very arrogant.'
Tulisa is said to be baffled by Kelly's attitude towards her, after Rowland apparently refused to speak to her during Sunday's results show.
A friend of Tulisa's told the Sun:
"She was expecting to bury the hatchet with Kelly on Sunday night. Kelly was having none of it.
"She had a major sense of humour failure and was trying to suggest Tulisa was deliberately trying to destabilise her.
"Tulisa's not going to go crawling to Kelly – she's too stubborn for that."
