The pair will meet in the ring at Wembley on May 31 after Froch retained his IBF and WBA super-middleweight titles in the first fight last November.
Groves was frustrated with the outcome as a controversial ninth-round stoppage clinched victory for Froch in Manchester.
Ahead of the second showdown, the pair attended a press conference at Wembley, where Froch shoved Groves in the chest while posing for photos on the pitch.
"[Groves] looked petrified actually so I'm just lapping it up and smiling," Froch told Sky Sports News.
"I went away quite happy from the press conference, so whoever says round one to George Groves for that... I mean people are saying round one, round two, round three, George Groves does a lot of that - round one to me, round two to me, round three to me.
"I don't even get involved in any of that stupidness. It's just noise - it comes in one ear and goes out the other to be honest."
Promoter Eddie Hearn has tipped the rematch to become the biggest fight in British boxing history.
