Keep calm and corset on.

Lourdes Leon posted a photo of herself modeling a daring lace-up bustier and low-rise jeans on her Instagram Story Wednesday, shortly before news broke that her mother, Madonna, had been hospitalized Saturday.

The 26-year-old, who makes music as Lolahol, stuck a pose at a Vans event in the risqué look, which she accessorized with a silver belly chain and matching bangles and rings.

She made sure to tag the skate brand in her Story, adding a kissy-face for good measure.

While it may be business as usual for the style star on social media, Page Six was told Lourdes stayed by her mother’s side throughout her several-day health ordeal.

We broke the news that the “Material Girl” singer, 64, was found unresponsive, rushed to a New York City ICU and intubated for at least one night over the weekend.

Her longtime manager, Guy Oseary, wrote on Instagram that she’d “developed a serious bacterial infection” requiring hospitalization, but that “a full recovery is expected.”

Madonna was discharged from the hospital Thursday, with the BBC reporting that she’s now “home and feeling better.”

Several of the pop legend’s other children, including sons David Banda and Rocco Ritchie, were seen arriving at her Upper East Side apartment Wednesday ahead of her homecoming.

A source told Page Six Madonna fell ill while “strenuously rehearsing” for her upcoming Celebration Tour, which was set to kick off in Vancouver on July 15 but has been postponed in light of her medical crisis.
