The rugby player dated Monica Irimia back in 2007 (who knew?), and during their romance glamour model Larissa Summers claimed he cheated with her.
In light of Danny spending more and more time with his ex Kelly following the breakup of her relationship with Thom Evans, Margit Irimia has spoken out to warn the 'Celebrity Juice' star off Danny.
"Monica didn't trust him because he was very immature."
After Kelly split with long-term love Thom last month, she denied that Danny had anything to do with the split.
However, the pair appeared to confirm their romance when they went on a Valentine's Day date together earlier this month.
Kelly is due to make her debut as a 'Celebrity Juice' panellist on Thursday night, stepping in for new mum Fearne Cotton.
