*Kelly Rowland had a lip-synching moment recently when her nerves got the best of her. She usually goes through a pre-concert ritual – to blow in and out of a balloon until she’s gasping for air- but that didn’t work this time. So she opted to lip-sync during a concert at the P.C. Richard & Son Theater in TriBeca.

A source said Rowland also lip-synced at 103.5 KTU’s Beatstock last month. Kelly’s rep said she sang “live to track” — meaning she sang along with a recording — because she was congested and didn’t want to disappoint her fans. “She does not use balloons for anxiety, but rather to warm up her vocals,” her rep added.
