The Las Vegas catch phrase, “What happens here, stays here,” may soon be a thing of the past.

Sin City officials could be rolling out a new top-secret tourism campaign, with the help of rock legends Aerosmith.

Lead singer Steven Tyler used the phrase “what happens here, only happens here” to a concert audience four times last week, according to reporting from the Las Vegas Review-Journal.

According to the Reno Gazette Journal, the number of people traveling to destinations like Las Vegas plunged after the Sept. 11 attacks, forcing tourism officials to find a spark to draw patrons.

In 2002, R&R Partners developed "What happens here, stays here," which turned out to be a hit.

According to a post on Aerosmith’s Instagram, the new campaign could be launching on Jan. 26.
