Big Brother bosses are reportedly planning to axe Brian Dowling as host.
The former winner of the reality series has been hosting the show since its move to Channel 5 in 2011.
Emma Willis has been offered the job to replace Dowling as the show's main host, The Sun claims.
Willis is currently the presenter of spin-off show Big Brother's Bit On The Side, while she also appears on ITV's This Morning.
"Brian has been a great host but Emma is seen by channel chiefs as a true successor to Davina. They're talking to her now about taking over the role from the summer," a source said.
"Like Davina when she hosted the show, Emma's young, a mum of two, and very glamorous. The audience love her on BBBOTS, and execs want to capitalise on that.
"She's thinking it over, but it's a great opportunity and she would be mad to turn it down."
Dowling will reportedly have to be compensated should he be replaced, as he has signed on for another two series as host.
Bosses are said to be considering a swap of shows for the two presenters, but insiders have said that Dowling is unlikely to agree to what would in effect be a downgrade.
Big Brother will return for its 14th series in the summer on Channel 5.
