AceShowbiz - Watching Lady GaGa and Bradley Cooper in "A Star Is Born", everyone could not help falling in love, not only with their performance, but also with the pairing. Their chemistry was so strong that it continued even after the camera stopped rolling. Many people got to witness it when they delivered an intimate performance of "Shallow" at the 2019 Academy Awards, fueling speculations of affair between the two that had surfaced prior to their much-talked-about duet.

But being an artist that she is, GaGa insisted that her relationship with Cooper was strictly platonic and professional. "From a performance perspective, it was so important to both of us that we were connected the entire time," she explained on "Jimmy Kimmel Live!". "When you're singing love songs, that's how you want people to feel."

While these persistent dating speculations could be bothering, for some actors this may be a testament to their great acting and fans' infatuation with the characters, like what GaGa felt. "I guess we did a good job. Fooled ya!" she said.

And these "A Star Is Born" actors are far from being the first on-screen couple who are rumored to be dating in real life. Both on small screen and big screen, some TV shows and movie have created fictional lovers that look good together off screen as well. Without further ado, let's take a look at some of the most favorite on-screen couples whom fans are dying to see as lovers in reality.
