'Cheerleader' Remix -- Texans Cheer Team Recruited ... for Music Vid Shoot

The Houston Texans cheerleaders' have AWESOME timing, which is why they're about to co-star in a music video for the #1 song in the country, "Cheerleader."

TMZ Sports found out how the Texans ladies ended up in an impromptu video shoot with Jamaican singer Samantha J. It went down last month in Atlanta ... where the team and Samantha happened to be at the same cheerleading convention.

Samantha had recently teamed up with Omi to remix his huge hit, and sources at the convention tell us she got a blast of inspiration when she met the Texans cheerleaders.

We're told the convo was as simple as you'd expect ... "You're cheerleaders. I have a cheerleading song. Let's make a video."

The remix vid is due to be released any day now. Until then, enjoy the behind the scenes pics.
