Old Music Video
If you watch the No Doubt video for "Running" it looks like she gets tickled at the very end. It's just as the song is fading out, the band is walking along the beach towards the camera, and the drummer (I think) sneeks behind her and looks like he grabs her sides. She laughs and jumps forward a bit (no audio, just the song). You be the judge.
On that theme, in the music video "Put Your Best Dress On" by Steve Holy there's a quick tickle about a third of the way through. He is standing behind his wife in front of the bathroom mirror and she has her arms out to her sides holding a dress in front of her. He gives her a nice poke and she jumps, laughs, and smiles. One of my favs. (Again, no audio besides the song.)
In Andy Griggs' video, "Tonight I Wanna Be Your Man" there is a tickle towards the end. The husband and wife are standing in the bedroom and he tickles her for a second or two on the sides before they embrace and fall onto the bed. If you look closely you can see her say "Stop" or something like that.
There MIGHT be a tickle in the Shania Twain video, "What Made You Say That". (Boy talk about going out on a limb here!!!!!!) Right at the end, as the song is fading out, Shania is wrestling a bit with the guy in the video and it looks like he grabs her side and tickles. Her reaction suggests a tickle as she laughs and pulls/runs away but you be the judge. (OMG, if I've called out a Shania Twain tickle that wasn't real think of the TMF INFAMY hell I'd be in!!!!!)
Anyway to find these videos you can try ITunes or Yahoo! Music....that's where I usually go. Again, Gwen and Shania are possibles. The middle two are definites. Later!
