President Obama previously held the record for the most retweets on Twitter following his re-election in 2012, but had the title taken from him earlier this month when Ellen hosted the Oscars and tweeted a selfie along with a number of famous faces.
Celebrities including Meryl Streep, Jennifer Lawrence and Bradley Cooper all posed alongside the talk-show host for the selfie, which quickly became the most retweeted post in Twitter history.
While speaking on the 'Ellen' show via a live video link, Obama addressed having his record broken, saying: "I heard about that. I thought it was a pretty cheap stunt myself. Getting a bunch of celebrities in the background."
Obama also joked that Ellen had to bribe the celebrities to pose with her by "giving them pizza", which she was seen doing during the ceremony.
