"i love you tony and susan. in just under 5 hrs the world can listen to 'Love For Sale,' our last album. my greatest honor, a bittersweet joyous heartbreak. i will never be the same Tony. thank you for your gift to all of us," she wrote.

Her message was in response to Bennett's, who shared similar excitement about the project. "Susan and I tuned in for @ladygaga's special live performance to celebrate #LoveForSale. So glad we could all join no matter where we are in the world. Lady, your performance was fantastic as always. Proud to release the Love For Sale album with you tomorrow," he tweeted.

"Love For Sale" is Gaga and Bennett's second duets album, as the pair released "Cheek to Cheek" in 2013. On August 3 and August 5, Gaga and Bennett performed together at "One Last Time: An Evening With Tony Bennett and Lady Gaga" to celebrate his 95th birthday. Unfortunately, those performances were his last due to complications related to Alzheimer's disease. Despite his struggle, Bennett's music will continue to inspire musicians for generations to come.

Lady Gaga caused an emotional firestorm on Twitter with the release of "Love For Sale," her second — and last — duets album with Tony Bennett.

Fans flooded her post with reactions and it's clear she delivered with her new tunes. "Congratulations my love for another amazing show like only you do! Thank you for giving us so many emotions with your art. You are amazing please never forget that, we love you infinitely," one Little Monster wrote. Another added, "Her calling it their last album makes me emotional ... can't wait to hear it." A third fan wrote, "Thank you for sharing this music with us. Watching you perform this afternoon made me so ridiculously happy. So thank you for spreading that joy. As Tony taught you, dig deep, and you'll always find the nectar."

Gaga and Bennett have always been close, as she told Parade in September 2014. "I tell Tony every day that he saved my life," she said. Working with him was different than working with anyone else, she explained. ​​"When I came into this with Tony, he didn't say, 'You've got to take off all the crazy outfits and just sing.' He said, 'Be yourself.'"
