"Paraisos Artificiales" Play - Buenos Aires, Argentina - September 17, 2015
Michael Buble and pregnant wife Luisana cheer on her lingerie-clad sister as they take in her steamy stage show in Buenos Aires
Michael Buble and his wife Luisana Lopilato had a fun night on Thursday.
The couple watched her sister Daniela Lopilato perform in the play Paraisos Artificiales in Buenos Aires and both seemed to like what they saw as they cheered her on.
Lopilato even wore see-through lingerie and smoked a cigarette for her part in the small production. The actress also kissed her female co-star while on stage.
The Canadian singer and his 28-year-old wife kept it casual in matching dark denim jeans with black boots.
Buble wore a brown leather jacket with a black and white plaid shirt while Lopilato donned a dark blouse, red sweater and finished with a signature necklace.
However the couple was considerably covered up compared to the lacey lingerie Daniela donned for most of her performance, nearly exposing her entire rear to her brother-in-law sitting in the audience.
