Lady Gaga was spotted snogging her boyfriend as they arrived at Toronto airport, Canada.

The pair were touching down from a long flight from Seoul, Korea.

The mystery man, rumoured to be 23-years-old, has long been the topic of speculation. He is thought to be an entrepreneur. The pair were recently spotted snogging on a beach in Hawaii.

Another possible is that she's seeing model Johnny Markoudakis, who appears as her 1940s Guido boyfriend in her video 'Eh, Eh (Nothing Else I Can Say)'.
