Heidi Hamilton dishes about Lady Gaga, Bradley Cooper duet and everything Oscars

Lady Gaga, Bradley Cooper's 'hot' Oscars performance leaves Twitter, Tiffany Haddish drooling

Lady Gaga and Bradley Cooper's scintillating performance of "Shallow" from "A Star Is Born" at the 2019 Oscars left tongues wagging on Sunday -- and one of those tongues belong to famously loose-lipped Tiffany Haddish.

The performance contained some seriously intense eye contact between the pair, who starred as the star-crossed Jackson Maine and Ally in the hit, which won the Academy Award for best original song at the ceremony.

Towards the end of the performance, Cooper, 44, moved to sit very close to the 32-year-old "Joanne" crooner, sharing a microphone and a small piano bench together.

"I was like, 'Are they doing it?' It was so good," the "Girls' Trip" star told Entertainment Tonight at the Vanity Fair Oscar party, adding that the co-stars had great chemistry.

"That was hot!" Haddish, 39, wasn't the only person to swoon over Gaga and Cooper's performance. "If you try to tell me Bradley Cooper and Lady Gaga aren't in love, I am going to call you a liar. #Oscars," one viewer wrote.

An Oscars audience member tweeted, "Right after Lady Gaga and Bradley Cooper's performance ended and it cut to commercial, they ran back into stage holding hands to head to their seats and the entire audience cheered and applauded them. #Oscars2019 #WhatYouDidntSee."

While some speculated that Cooper's longtime girlfriend (and mother of his daughter) Irina Shayk would be miffed, it was the opposite: Shayk, 33, was seen giving Gaga a huge hug during the show.

During her acceptance speech, a tearful Gaga gushed, "Bradley, there is not a single person on the planet that could've sang this song with me but you. Thank you for believing in us. Thank you so much."

"At the end of the day, he knows that he's the best director in my eyes, and in all of our eyes as his cast," she said. "I know that he's so happy that we've all been nominated and that the film was recognized and we all feel really, really beyond elated for the recognition."

Top Critics Vent as 'Green Book' Tops Oscars; LA Times Critic Calls It Worst Best Picture Winner Since 'Crash'

Within moments of "Green Book" winning the Oscar for Best Picture, the Los Angeles Times published a story Sunday night by critic Justin Chang with the the headline: "'Green Book' is the worst best picture winner since 'Crash.'"

Chang wasn't the only critic happy to tell the world what he really thinks of "Green Book."

"Remember that this is the same organization that gave its top honor to 'Crash' - so not surprising but still, f-- it," wrote the New York Times' Manohla Dargis.

"Green Book" never had many fans in progressive circles. Though its fans saw it as an unlikely buddy dramedy with a message of hope, critics accused it of old-fashioned and even retrograde portrayals of racial dynamics at a time when American culture demands more complex and nuanced stories.

It also survived plenty of bad press in the week after it won the Golden Globe Award for Best Motion Picture - Musical or Comedy, as well as other Globes. Old stories emerged of Peter Farrelly flashing his penis as a joke on the set of "Something About Mary" two decades ago, and screenwriter Nick Vallelonga apologized for an old tweet agreeing that Muslims had celebrated in New Jersey after 9/11.

Oscar voters looked past the criticisms, giving the film not only Best Picture, but also giving Best Supporting Actor to Ali and Best Original Screenplay to Vallelonga, Brian Hayes Currie and Farrelly.

"Just gonna leave this here," The Huffington Post tweeted. "This" was a piece entitled "'Green Book' Is As Disappointing As It Is Tone-Deaf On Race."
