Updated from April 6 with new tweet from The Rock on April 8.
A black t-shirt sporting the wrestler's iconic "brahma bull" has sold out after being worn at World Wrestling Entertainment's (WWE - Get Report) Wrestlemania this past Sunday, The Rock confirmed to TheStreet on Twitter. In a follow-up tweet, the Hollywood star -- whose real name is Dwayne Johnson -- said the second product in his four-part collection with Under Armour will see a "major launch" next week.
@BrianSozzi Thx buddy! These shirts are the start our UA capsule. The 2nd thing from Project Rock will have a big launch next week.— Dwayne Johnson (@TheRock) April 6, 2016
@BrianSozzi And I think the shirts sold out in record time for UA. I'll get official word by tonight from execs ����— Dwayne Johnson (@TheRock) April 6, 2016
On Friday, presumably after The Rock talked with Under Armour execs (see above tweet), he shared a new tweet with TheStreet.
We're gaining our apparel footing. Officially SOLD OUT in record time. Thank you everyone. Enjoy. More to come.. https://t.co/xJrvkpkSD5— Dwayne Johnson (@TheRock) April 8, 2016
An Under Armour spokeswoman did not reply to a request for comment.
The t-shirt is the latest Under Armour item inspired by The Rock to be met with blistering demand, no doubt helped by the star's huge social media presence. As TheStreet reported on March 22, the wrestling legend told his 46.7 million Instagram followers that the first item in his partnership with Under Armour -- a gym bag -- had been met with ferocious demand. "100% SOLD OUT -- bags are now an instant collectors item," said Johnson at the time.
He also teased upcoming product launches -- "Coming soon will be THE training shoe of all training shoes, training gear, lifestyle gear and some very cool technology."
Serious interest in a gym bag and t-shirt likely gives Under Armour confidence in the return potential of its most recent celeb signing. The actor and Under Armour inked a long-term marketing deal in January (for an undisclosed amount) under which the apparel maker will design products including footwear, apparel and accessories inspired by Johnson's current films.
Johnson joins a suite of athletes signed by Under Armour that includes Golden State Warriors guard Stephen Curry, No. 1-ranked golfer Jordan Spieth and Carolina Panthers quarterback Cam Newton.
