A weather girl was left embarrassed after she predicted that the weekend after Valentine's Day would be "slow and slutty".

Danielle Grant, who works for KREM 2 in Spokane, Washington, made the slip on Monday after telling viewers that February 14 would be a great day to hang out with your significant other.

"The weekend, so far so good, should be dry but in the 40s, slow and slutty... slutty? Steady!" she said.

The blooper, uploaded on YouTube, has gone viral with 27,000 hits.
