Caitlyn Jenner is kicking her model career into gear. The reality star confirmed a long-suspected collaboration with H&M Sports on Thursday night. “Backstage with @hm!” she wrote, along with a photo of her modeling some sports outfits. The 66-year-old was seen decked out in black workout clothes as she sat on a gym bench surrounded by weights. Rumors have swirled for months about a potential modeling campaign with the store and E News reports that Jenner will be the face of the retail giant’s new sports line. “So proud to be part of their inspiring #HMSport campaign,” she continued. The “I Am Cait” star teased more details in the athletic partnership were to come, adding the hashtags “#MoreisComing” and “#StayTuned.” The retail chain also celebrated the news, sharing the same photo after Jenner’s tweet. “Behind the scenes with the strong and beautiful @Caitlyn—Jenner. Stay tuned for more! #HMSport,” they wrote. It’s been nine months since Jenner came out about her transition. The H&M news comes on the heels of the transgender activist’s first steps into the fashion world. Two weeks ago, she announced her lipstick with MAC cosmetics. The partnership with the beauty company features a lipstick shade of cream sheen aptly called “Finally Free,” with proceeds from the $17 tube going to the MAC AIDS Fund Transgender Initiative. The lipstick goes on sale April 7.
