Denise Welch appears to hit out at former rival Coleen Nolan on CBBBOTS after falling out in 2013

DENISE Welch appeared to throw shade at her former rival Coleen Nolan last night, admitting she's "good" at being "passive aggressive".

The pair famously fell out in 2013 over some comments Coleen made about mental illness in a magazine interview.

And while they've made up since, Denise, 58, couldn't resist giving her views on Coleen, 51, when she appeared on Rylan Clark-Neal's Celebrity Big Brother's Bit on the Side show last night.

As Rylan brought up Coleen's tendency to chat about her housemates behind their backs, he said to Denise: "You know her better than anyone, come on."

As Denise hesitated, Rylan and the crowd immediately shouted out, to which Denise said: "I think she has got a strategy."

She added: "Coleen is very good at the passive aggressive things.

"Like going in the garden and hearing stuff, and coming back in and saying 'Oh god, you would die if you heard what they're saying about you!'"

Coleen and Denise previously fell out three years ago after Coleen gave her views on mental illness in an interview with Best magazine.

She said at the time: "Obviously I feel sorry for anyone who, through no fault of their own, suffers depression.

"But I'd like to know how many celebs with a chemical imbalance in their brains have used drugs."

She later added: "Is it a coincidence Stephen Fry, Kerry Katona and Denise Welch have all admitted to cocaine use and are now bipolar, while others suffered ­depression and breakdowns?"

Denise later hit back at the hurtful comments in her column on the Birmingham Mail, saying: "'I’m not bipolar and I have made no secret of the fact that my descent into the hell of self-medication was a result of suffering depression and not the cause of it."

She added: "The fact that Ms Nolan had not heard of bipolar until a few years ago makes her unqualified to talk about the illness she clearly has no understanding of."
