Hmm... Where have we heard this before...
Not only are they both A-list celebrities, but they're both officially in Taylor Swift's squad!!
The actress stopped by Thursday's show to promote her new thriller Money Monster, when Ellen showed footage of Roberts on stage with the popstar during the Santa Clara, California concert on her 1989 tour.
"I've never seen this — I don't think that should actually be viewed."
After Ellen remembered her own 1989 experience in which she wore a sparkly unitard, Roberts defended her on-stage attire — explaining that she had no idea she was going to be in front of 50,000 people, because Swift asked her only moments earlier backstage!

Later on, the 48-year-old showed off her sales skills playing the game Pitch, Please — where she had to sell the audience a product that was hidden from her view.
Unknowingly selling the audience a collection of kinky toys — including handcuffs, a blindfold, and a whip — the actress still managed to whip up a pretty convincing sales pitch!
Ch-ch-check out the clip (below) to see her priceless reaction when she found out what she was selling!
