The This Morning favourites are in the Austrian capital to celebrate Eamonn's 60th birthday this week (03.12.19).
In the caption of a photo from the trip posted to Instagram, Eamonn revealed that the holiday was a surprise present from Ruth.
He had no idea they were going to Vienna, and when he arrived, his grown-up children were all waiting for him there!
Eamonn wrote alongside the pic, which showed him beaming next to Ruth in front of a festive scene: "Whisked off by Ruth on a complete mystery trip for my birthday.
"Ended up in Vienna with my children waiting there for me!
"Never been before - can't wait to come back. Great time in a truly majestic city."
In the comments, Eamonn's celeb pals rushed to wish him a happy birthday.

Former EastEnders star Martine McCutcheon wrote: "Happy Birthday darling."
Saturday's singer Mollie King, who has previously served as a guest host on This Morning, said, "How gorgeous!" with a string of heart emojis.
Coleen Nolan from Loose Women told him: "Hope you've had the best time, you deserve it! Love you both!"
And presenter Kate Thornton said: "Wow! What a wonderful surprise. Happy birthday - send you all my love."
His fans also rushed to the comments, with one writing, "Happy birthday Eamonn, what a wonderful surprise" and another telling him, "What a lovely surprise for you", while a third said, "Fab, enjoy folks!"
Eamonn tied the knot with Ruth in 2010 and they share one son, 17-year-old Jack.
He also has three children from his marriage with ex-wife Gabrielle - Declan, 30, Rebecca, 28 and Niall, 26.
Earlier this month he did just that, after they listened to You're Beautiful by James Blunt while introducing the episode's segments.
Eamonn, who claimed to have requested the song be played for Ruth, then joked that he was in likely for a "fun night" with his wife.
