The model, 32, designed the underwear for its new Rosie for Autograph collection.
Ex Victoria’s Secret Angel Rosie recently announced a make-up masterclass with artist Marc Reagan in New York.
She captioned a sweet sH๏τ of the pair with: “@makeup.marc and I can’t wait to see you all in almost one week at the New York @roseinc Masterclass.”
Rosie has been in a relationship with actor Jason Statham since 2010 and the pair got engaged three years ago.
They share a son, Jack, who was born in June 2017.
Last year she opened up about how his birth left her suffering from terrible acne.
She told PorterEdit at the time: “I’ve never had perfect skin, but throughout the pregnancy it couldn’t have been better…
“Six months after [the birth] the acne started. It’s sort of a depressing thing, so mortifying.”
And earlier this year she revealed her battle with her skin has even caused her to ditch eggs and dairy from her diet.
She said on her YouTube page: “I get a lot of people asking me what my skin type is, well on a good day, I would probably have just a couple of spots, and on a bad day, it could be a lot.
“I’ve always had a little bit of acne because it’s something my mum had. It’s something I’m always trying to better so I’m quite diligent about my skincare routine.
“So currently I’m cutting out eggs and dairy which is really boring because they’re all my favourite things, but there is nothing better than having good skin.”
