Bennett told showbiz411.com that he hopes to record an album of Cole Porter tunes with Lady Gaga.
Bennett, who will celebrate his 90th birthday in August 2016, said he hopes to mark that occasion with a concert in Central Park.
"Tony Bennett and Lady Gaga: Cheek to Cheek," which features classic jazz standards in both vocal duets and solo performance, was released on Streamline/Columbia/Interscope Records in September 2014.
