Susan Sarandon and Piers Morgan are engaged in a Twitter war over the former's boobs.
It all started last Saturday night, when Sarandon took to the stage at the 2016 SAG Awards to pay tribute to all the stars who had passed away over the past year.
An in memoriam segment often takes place at ceremonies such as this.
But the person presenting it does not often wear the sort of revealing top that Sarandon chose to don:
Some viewers believed this was inappropriate attire for the actress to wear, considering the sad theme of her presentation.
And Piers Morgan was one of these viewers.
“Would Susan Sarandon wear this to a funeral? No. It was thus horribly inappropriate for an In Memoriam tribute,” Morgan Tweeted on February 3, along with a picture of Susan's revealing ensemble.
It's a pretty good point, but Sarandon clearly did not agree with it.
And she responded on Thursday in a hilarious manner.
"Today’s #TBT is dedicated to @piersmorgan," Sarandon wrote as a caption to a throwback photo of herself in a white bra while starring in the 1975 cult movie The Rocky Horror Picture Show:
Not to be outdone, however, Morgan then shot back with the following (disturbing) image:
“Today's #TBT is dedicated to @SusanSarandon,” he wrote alongside a Photoshopped image of himself shirtless and draped in velvet... while wearing a Burger King medallion.
This back-and-forth prompted numerous Twitter users to come to come to Sarandon's defense by sharing online snapshots of their own cleavage.
In other words: this has become the greatest celebrity feud of all-time.
"Just for the record, @SusanSarandon, I think your cleavage is magnificent," Morgan Tweeted later Thursday night. "I'd just keep it hidden for ‘In Memoriam’ tributes."
We agree with both of those sentiments.
