Jessica, 30, and Nick, 36, both dined out with their new partners Eric Johnson, 31, and Vanessa Minnillo, 29, at Hollywood hotspot The Red O last Thursday.
But when she was asked about the incident at the Women's Conference in Long Beach, California, yesterday, she told American newspaper USA Today they did not talk.
Simpson said: 'He was at the same restaurant, I didn't speak to him.'
The reality TV star did speak more fondly of her current beau, former NFL star Eric.
She said: 'He definitely makes me very happy, he brings out a lot of light in me and makes me very comfortable being who I am.
'It's nice to be with somebody who praises you for the right reasons.'
But the star isn't ready to head down the aisle again just yet.
The actress-singer added: 'Wedding? Right now I'm focused on my precious nephew and godson.'
