It comes after the Bake Off judge, 53, allegedly fell out with his former co-judge when at last year’s show following his treatment of his former partner, 54, a close friend of Mary’s.
Paul and his wife of 20-years, who have a 16-year-old son together, announced their split in November 2017, with the chef now dating 23-year-old Summer Monteys-Fullam.
He’s out: Paul Hollywood has reportedly been axed from the BBC’s Good Food Show and replaced by his ex wife Alex – who will appear alongside Mary Berry at the Birmingham event
A source told The Sun: ‘Mary has made it clear were her loyalties lie – and it’s not with Paul.
‘She’s still upset with how he behaved with Alex and is not even making an attempt to get to know Summer.
‘And to avoid any awkwardness with Paul, she’s more than happy to work with Alex and help boost her profile as a budding celebrity cook.’

Alex will reportedly join Mary on stage when they attend the occasion at Birmingham’s NEC in June.
During last November’s BBC Good Food Show, Mary refused to join Paul during his cooking demonstration, with a source at the time insisting she said ‘no quite forcefully’.
The 83-year-old also apparently refused to be pictured with her former Bake Off colleague, while snubbing his new girlfriend.
MailOnline has contacted representatives for Paul and Alex Hollywood, as well as Mary Berry.

Meanwhile, the publication recently claimed Alex became embroiled in an argument with Paul’s new girlfriend while shopping in a Marks and Spencer’s in Canterbury, Kent, last month.
The fracas is even alleged to have resulted in police being called, having initially started at the checkout before spilling out into the car park, with one witness describing the language used as ‘disgusting’.
Summer’s mother Sabina defended her daughter and took the TV baker’s former wife to task over her alleged nasty behaviour.
Summer’s sister Saskia captioned the video, which has since been viewed thousands of times, ‘the truth is finally out’ before it cuts to her mother Sabina, who speaks for five minutes outlining what she understands to be the truth of the matter.
She says the attack was categorically started by the baker’s ex wife, who she says verbally abused her 23-year-old daughter as she went shopping.
But according to the Mirror, a spokesman for Alex insisted: ‘Alex has kept a dignified position throughout the last 14 months, which have been extremely challenging, and continues to do so.
‘Alex was shocked to bump into Summer in her local supermarket, but even in that difficult situation she did not, and would not ever, verbally abuse anyone.’
