Ali and Jackson reunited on-stage for a steamy performance. 

Bradley Cooper and Lady Gaga had so much chemistry during their Oscars performance of "Shallow," that social media was literally rooting for them to conclude with a kiss. 

But while Gaga is newly single – the actress and her long-term fiancé Christian Carino split just mere weeks ago – Cooper is very much taken, by Russian supermodel Irina Shayk, his girlfriend of four years. 

Shayk saw their passionate performance – which is sending the rumour mill into an almighty spin – from the front row of the Oscars crowd and was the first on her feet to congratulate the two on the now Oscar-winning song's conclusion. 

In fact, after Gaga came back to her seat after winning her Oscar, she and Shayk hugged at their seats.

Upon receiving the gong, Gaga's spoke emotionally about why Cooper was the only person who could've made the song work the way it did with her.

"Bradley, there is not a single person on the planet that could've sung this song with me but you," she said, naming him immediately after she thanked her family.

"Thank you for believing in us. Thank you so much."

Shayk, Cooper, and Gaga were all seated together in the front row of the ceremony, with the model placed between her man and the singer-turned-actress.

The questionable seating arrangement had Twitter users speculating about possible tensions, but the Shayk's reaction to the duo's set just shut all of that gossip down.
