Lady Gaga never fails to surprise and amaze us. This time she did it with her 88-year-old singing counterpart Tony Bennett.

Lady Gaga and Tony Bennett performed a live medley of "Cheek to Cheek" songs on "Strictly Come Dancing" on BBC 1 (UK).

The singer looked chic in her retro look. Lady Gaga wore a grey satin dress coupled with a black afro-hair wig on the BBC show.

During the show Lady Gaga was seen dancing provocatively around Tony Bennett.

Later she told her 42.6M Twitter followers: 'Loved performing on @bbcstrictly with Tony!'

I bet the audience also loved the performance of Lady Gaga and Tony Bennett.
