A lonely Lady Gaga was spotted stepping out after her song with Bradley Cooper, “Shallow,” secured the top spot on the Billboard Hot 100. Her leading man, on the other hand, was spotted happily reuniting with his “Alias” co-star Jennifer Garner a day prior.

On Monday night, Lady Gaga was photographed making her way to a dinner with her team to celebrate the achievement, which she previously accomplished back in 2011 with her song “Born This Way.”

For the outing, Gaga opted to sport an all-black ensemble comprising a thigh-grazing dress with statement-making sleeves and a long train. The singer-actress matched her outfit with a pair of black heels and a black bag.

The Hollywood star also had her hair pulled back into an updo and she accessorized with dazzling diamond earrings. For the night out, she wore a rosy blush and coral gloss and rocked a shimmery yellow and white eye shadow.

While she wasn’t technically alone during the outing, it was regretful to see Lady Gaga celebrating the success of her song without her duet partner, Cooper. The two previously made a lot of buzz for their live performance of the song at the Oscars.

The heartwarming and lovely performance even fueled rumors that Cooper could be cheating on his baby mama, Irina Shayk, with Gaga. But Gaga quashed such rumors when she made a guest appearance on Jimmy Kimmel’s late-night talk show. She insisted that their moving duet was purely staged.

Meanwhile, Cooper was spotted at Garner’s house last Sunday. The former co-stars had dinner together and they were actually joined by Shayk and her and Cooper’s 1-year-old daughter Lea De Seine. Even Cooper’s mother, Gloria, was present at the gathering, according to People.

Sources said that Cooper and Garner have gotten really close since working together on their spy-themed television show. In the series, Cooper played Will Tippin, a good friend of Garner’s character, Sydney Bristow. In real life, the two have fostered a remarkable friendship.

Garner even greeted Cooper on his 44th birthday early this year. Ben Affleck’s ex-wife shared a picture of her and Cooper on her Instagram and she jokingly captioned the post, “I taught him everything he knows. Happy Birthday, Bradley. Go get em tomorrow. We are all so proud of you.”
