The 41-year-old reportedly found former toy boy lover, 24, outside her new home after an argument between the pair.
According to insiders, cage fighter Tom had downed prescription drugs and alcohol and the police had to be called.
“Danniella was absolutely horrified. Their relationship has been very fiery. She finally had the strength to end it properly but Tom is making things very difficult for her.
“She has enough problems of her own, having lost her home recently. She has children to care for and provide for.”
Poor Danniella. We’re sure this is the last thing she wanted, especially as she’s just returned from a relaxing break to Egypt.
The mum-of-two was there to help X Factor singer Chris Maloney, 37, celebrate his engagement to partner Gary Doran.
We don’t like being the third wheel at the best of times, and being stuck in the middle of another couple’s engagement sounds like an awkward nightmare, but it looks like Danniella had a good time.
In one picture she is wearing a coral bikini and riding a camel with the happy couple.
Chris tweeted: “Me and @garydoran00 had a fantastic engagement here in Sinai Desert Sharm el sheikh Egypt with @westbookdanni [sic].”
