Lindsay Arnold possible tickle

I was just watching this video on youtube that Lindsay and her husband made and it looks like he tickles her at 1:20. If you look closely at his hand it looks like he is wiggling his fingers into her sides a little bit and she has a little bit of a reaction to it. She was laughing before he touched her so I'm not sure if she is actually being tickled or if I am just seeing things lol. I have posted a video previously of Sam tickling Lindsay so that makes me more inclined to think he is tickling her.

I think she may have been tickled during the video. Because notoriously he does the movement you referred to - which is a typical tickling movement ...

However, as she was laughing before, I had the same doubt as you. But I think it's a ticklish reaction, she takes his hand away later ...

Looks like a tickle to me
