Chris Brown & Rihanna Showdown Planned

Chris Brown & Rihanna are set for another head-to-head clash a week after they faced off against each other on rival American TV interviews.

Brown and Rihanna appeared on MTV and ABC news show 20/20 respectively last Friday, both announced upcoming tours on the same day and have new albums released two weeks apart later this year - and now their new videos will debut on Friday.

Brown will show his new promo for Crawl on the Wendy Williams Show and Rihanna will debut her video for Russian Roulette hours later on this week's 20/20.
