According to Bennett himself.
Looks like LG5 might be a little later than expected.Multiple sources are claiming that Tony Bennett confirmed a follow-up to his 2014 album with Lady Gaga at a show in Idaho last night. He apparently stated that they have a new record which will be released this August to coincide with his 90th birthday - Lady Gaga's idea, apparently. The 89 year old jazz superstar is said to have waxed lyrical about the "Bad Romance" singer, and even joked that everyone should go out and buy her next album because "she needs the money." Naturally, Gaga's fans have met the news with, um, measured enthusiasm.
