DWTS' Ballas CAUGHT with IDOL's Pia!

She's said they "vibe well together" – and apparently they like to dine together, too. Dancing with the Stars pro Mark Ballas and recent American Idol castoff Pia Toscano stepped out together at Asia de Cuba inside West Hollywood's Mondrian Hotel, reports People. The duo arrived around 8:30 p.m., and though they weren't overly romantic, a source says it seemed like the two were on a "second date," adding that they were extremely polite and in good spirits.
