Aljaz was later seen Facetiming Lara, who lives in Slovenia.
The siblings often spend time together.
When Lara visited her brother back in July, she shared a heartfelt message to her followers: "23 years ago, when @aljazskorjanec took his first dance lessons, I wanted to dance, just like he does.
"He was and he still is my idol and inspiration.
"Those loud heartbeats and very loud screaming is just a little bit of what I felt when I saw how he dances for people every day and how people love him! Dear brother, I love you!"
Aljaz, who's dancing with Viscountess Emma Weymouth in this year's series, appeared on This Morning ahead of their successful Movie Week dance.
Dancing the foxtrot to the theme from the Downton Abbey movie, they revealed they were emotional the first time they found out.
Aljaz revealed: "It's beautiful music – the theme tune to Downton Abbey – it's so powerful. We actually cried when we heard it for the first time."
The couple were awarded 28 points, and were fifth on the leader board.
