The highly-anticipated residency at Park Theater at the new Park MGM resort kicks off April 6. The band had 18 previously scheduled dates from April through July.
The Rock and Roll Hall of Famers just announces new shows September 21, 23, 26 and 28. October 1, 3, 6 and 8; November 14, 16, 19, 21, 24, 26, 29 and December 1 and 4.
Tickets for the newly-added shows go on sale February 16.
"Sin City, we are coming back for round two!" says the band in a statement. "We've added 17 new show from September 21 - December 4 to our 'Deuces Are Wild' Las Vegas Residency at Park Theater at Park MGM!"
A limited number of tickets to the spring and summer shows are still available.
"We want to do a show that still has Aerosmith and all the guts of Aerosmith but is something you would never see before," guitarist Joe Perry told NBC's Today show last August.
Drummer Joe Kramer added that the residency celebrates Aerosmith's legacy in a venue conceived and built for live sound.
"As soon as you walk into the Park Theater, it's going to be all Aerosmith," Kramer said.
In other Aerosmith news, the band is finally receiving a star on the Hollywood Walk of Fame this Thursday, Valentine's Day.
