Has Pan Am been canceled?

According to actress Karine Vanasse, who plays French flight attendant Colette on the ABC show, it's over.

Well, we received THE call, #PanAm is only coming back for one more episode after Christmas. But up to the end, we give it our all! the Canadian actress wrote on Twitter Tuesday afternoon.

But is it really the end? Not so fast, according to ABC.

Nothing has changed . . . we are not canceling 'Pan Am.' We are still in production and will continue to be in production finishing the original 13 episodes plus one more additional one, ABC said in a statement obtained by several outlets.

We have one more original episode this coming week, Dec. 4 and then will return in January with new episodes, airing all of them. 'Pan Am' is still in contention for next season. We won't know about that until our upfront announcement in May, the statement added.

Even with a new season, the show will be taken off the air to make room for the midseason series, GCB, insiders told The Hollywood Reporter on Tuesday.

GCB, also known as Good Christian Belles, stars Kristin Chenoweth and Leslie Bibb and is produced by Beverly Hills, 90210 and Melrose Place creator Darren Star.

Despite a strong series premiere in September, with more than 11 million viewers tuning in, Pan Am has gradually underperformed during its Sunday 10 p.m. slot. Before Pan Am, the 10 p.m. slot was occupied by the family drama, Brothers & Sisters, starring Sally Field, Rachel Griffiths and Calista Flockhart. In May, the show was cancelled after five relatively strong seasons on ABC.

Starring Vanasse, Christina Ricci, Michael Mosely and Kelli Garner, Pan Am documents the personal and professional lives of the pilots and stewardesses of the airline that once ruled the world. Set in the 1960s, the period drama was one of the favorites going into the fall TV season, along with the now-cancelled Charlie's Angels and The Playboy Club.

With Tuesday's Tweet from Vanasse, Pan Am has remained a trending topic on the social media outlet.

'Pan Am' has been cancelled. American Airlines is in Chapter 11. 'Catch Me If You Can' flopped on Broadway. Enough with pilots, wrote one user.

'Pan Am' is doing well internationally. They're filling the order, and adding one more. If it gets picked up, I'll buy you all a drink, wrote another.
