After the New York Post reported the Green Light singer pulled a woman into a bathroom and shared "a steamy make-out session" with her behind model Chrissy Teigen's back at a club last week, Chrissy took to Twitter to joke that John wanted to kill her to make way for the mystery woman.

She tweeted: "@johnlegend my tummy hurts and I think it's the chicken you made me last night are you trying to kill me so u can be with your bathroom GF? (sic)"

John joined in on the gag, replying: "My tummy kinda hurts too. It was a murder-suicide attempt"

However, Chrissy - who has been engaged to John since 2011 - later seemed to have put the incident out of her mind and moved on to tweeting about food cravings.

She wrote: "In this day of ... online petitions, why can't we be serious and get the ball rolling on bringing back Rice Krispy Treats cereal?

"I am not talking about rice krispy treat squares. I am not talking about rice krispy cereal. I am talking about rice. krispy. treat. cereal!

"Buy it on Amazon? You can buy clear Pepsi on Amazon too. I need this ... back mainstream style (sic)."
