Katheryn Winnick 2017: 'Vikings' Season 5 Star Teases Possible Conor McGregor Casting For History Series [PHOTO]

The fifth season of "Vikings" might be losing Travis Fimmel as Ragnar Lothbrok, but the series will be getting some awesome new characters as well. Fans already got a glimpse of Jonathan Rhys-Meyers as Bishop Heahmund and Adam "The Edge" Copeland will portray legendary warrior Ketil Flatnose. But is it possible that Katheryn Winnick has just teased the addition of mixed martial artist Conor McGregor to the "Vikings" Season 5 cast?

Katheryn Winnick has actively been keeping fans updated on what's happening behind the scenes of "Vikings" Season 5. The "Stripped" star's Instagram account features awesome photos of her costars as well as incredible teasers on what to expect when the series returns to History. Now Winnick's most recent post presents the possibility that Conor McGregor, who has been confirmed for a minor role in "Game of Thrones" Season 7, should join her show's cast.

The "Vikings" Season 5 actress has recently posted a new picture on Instagram which features Katheryn Winnick with Conor McGregor. The caption reveals that Winnick "bumped into" the upcoming "Game of Thrones" Season 7 star and asks her followers whether McGregor should be cast in the History series. Not surprisingly, fans responded enthusiastically to the idea.

Could Conor McGregor join Katheryn Winnick and the rest of the "Vikings" Season 5 cast? Will Lagertha possibly find a new ally in the current UFC champion and future "Game of Thrones" star? There is no confirmation just yet, but fans should keep their fingers crossed. In the meantime, fans can expect to see more of Winnick in two new films in 2017. She will play Laurie Chambers in "The Dark Tower", which premieres on July 28, as per Variety. The Gerard Butler disaster flick "Geostorm" is scheduled for release on October 20.
