Hollywood star, Rachel McAdams, was born in London, Ontario but this summer she'll be asked the question - 'Who do you think you are?' and the answer may have a connection to the capital.
McAdams is one of the stars featured in the latest season of the TLC reality show that has celebrities examining their family tree.
A new promo for 'Who Do You Think You Are' shows Rachel McAdams and her sister Kayleen driving along Wellington Street beside Parliament Hill.
If you look closely you can see the Rideau Centre in the background.
There's no word on how the McAdams girls are connected to Ottawa but all things will be revealed when her episode airs on August 6.
