Although it’s been a while since we’ve seen Robin Sparkles on American television (she was discovered back in November 2006), fans won’t have to wait much longer.

Come April 21, How I Met Your Mother‘s favorite Canadian pop star (a.k.a. Robin’s early years) will be showing us a much softer side.  Here’s a preview of her Debbie Gibson-esque ballad “Sandcastles in the Sand.”  (Check out the other ‘80s icons in the clip.)

If you haven’t had the chance to experience Robin’s breakout hit, “Let’s Go to the Mall”, you can see that video after the jump.  Those wanting even more Sparkle can also learn about the acid wash loving singer through her MySpace page.
