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.

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.
