Long may she 'Reign' — Mary, Queen of Scots is finally pregnant!
Oh baby — this is awkward.
It's no secret that Reign's leading lady Mary (Adelaide Kane) has been desperately trying to get pregnant for months, and in tonight's all-new episode fans are in for a shocking revelation: Not only will Mary discover that she finally has a royal bun in the oven, but Catherine (Megan Follows) knew this news way before Mary did — and we've got your exclusive sneak peek to prove it.
Adding to the uncomfortable, Catherine barges in to express her excitement at being a grandma in the middle of Mary's love-making celebrations with Francis (Toby Regbo)! (Who else thinks Catherine is most definitely in the lead for most overbearing mother on TV?)
So how could Catherine tell that Mary is with child? Her spies, of course. Oh, and this 16th century pregnancy test: "A few weeks ago I had your chamber-pot tested," Catherine shamelessly admits. "It's the usual exam, it's horse urine and wine — it's very reliable."
And despite the fact that her daughter-in-law in laying naked in bed with her son, Catherine offers Mary one particularly amazing piece of advice: "Your figure is going to go to hell anyways so you might as well eat up. You are feeding the future king of France."
Take a look at our exclusive sneak peek of tonight's episode to see all of the boundary-crossing baby buzz for yourself!
