Ellen DeGeneres is desperately trying to cling on to her record of posting the most re-tweeted tweet ever, and has enlisted the man who snapped the famous Oscars selfie, Bradley Cooper to help.

DeGeneres is defending her title from highschool student Carter Wilkerson who is trying to collect 18 million retweets to win a year's free supply of chicken nuggets from Wendy's.

So far he is at 3 million tweets, edging closer to DeGeneres record of 3.3 million.

In a segment on her TV show last week, DeGeneres and Cooper ran a spoof PSA announcement asking for help.

The TV host is asking people to retweet her tweet each time they retweet Wilkerson's, so that she can retain her title.

"We put our heart and our soul in to that selfie," said Cooper.
