What happens in Vegas... You know the rest.
That's been the catch phrase Las Vegas has used for nearly two decades.
But now the slogan could be a thing of the past.
The city could be using a very popular artist to roll out a new top secret tourism campaign.
Steven Tyler from Aerosmith introduced "What happens here, only happens here" at his concert in Vegas last week.
There's speculation Tyler may be part of the city's plan to launch a new slogan.
Aerosmith is reportedly involved in a top secret surprise happening in Las Vegas on January 26.
