Former Philadelphia Phillies shortstop Jimmy Rollins’ unexpected Instagram posts about women’s underwear were promotional messages for Pretty Kitty Klub, a company he co-founded, according to the brand and the supplied report. The posts prompted online speculation that his account had been hacked, but the company’s statement identified him as a co-founder and explained his previously limited public presence with the business.

Rollins, 47, is a retired Major League Baseball player who won the National League Most Valuable Player award in 2007. The report also describes him as working as an analyst for TNT Sports. His recent social media activity introduced followers to the underwear brand after an earlier post about postseason defense.

One post shared screenshots of text messages praising Pretty Kitty Klub. Rollins wrote that the feedback suggested the brand was helping couples, adding a joking reference to improving married life. The shift in subject matter from baseball defense to lingerie led some followers to question whether the posts were genuine.

A subsequent post featured models wearing the products and referred to the approaching holiday season. Rollins encouraged men to consider the products as gifts and told women that comfort and an attractive design could go together. He also noted that the models and scenes were real, while artificial intelligence had helped with editing.

Some commenters reacted with surprise, while others responded playfully to the promotion. One person recalled having a life-size poster of Rollins as a child and joked about buying the product as a Christmas gift. Another commenter referenced Rollins’ Phillies career and said he would consider the recommendation.

Pretty Kitty Klub told the New York Post that Rollins is a co-founder. The company said he had maintained a more private role until the previous week, concentrating on the company’s long-term vision, strategic growth and business development. It said that was why he was not then featured on the company website.

The supplied report does not provide details about when the company was founded, its products beyond the posts described, or the scale of its business. The confirmation addresses Rollins’ connection to the brand and his role, rather than offering further information about its operations.
