Pink Poses on a San Diego Beach 4 Days After Postponing Texas Show Due to Illness: 'Ready for Y'all'

Pink is making a return to the stage!

The Grammy winner, 44, was seemingly back to good health on Tuesday, when she shared a smiley snapshot from a San Diego beach via Instagram. (Just last week, the star had to postpone a tour stop due to a sinus infection.)

“Learned some new material this morning … ready for y’all @snapdragonstadium #sandiego #heaven #healed #summercarnivaltour," Pink wrote in the caption ahead of her upcoming show.

"Absolutely gorgeous! Glad your [sic] feeling better!" read one fan comment.

"I've waited 23 years to see you play and I finally get to tonight. Cannot - f---ing - wait!" another fan wrote. "Thank you for being you, your art, your energy, and just everything! ❤️"

The "So What" singer announced in an Instagram post on Friday that she was postponing the Arlington, Texas, stop of her Summer Carnival tour after suffering a sinus infection.

“Hi everyone. I’m very sorry to report that I have come down with a bad sinus infection, and the doctor advised me not to perform tonight,” Pink wrote at the time. “I am so disappointed. You know I do everything in my power to never miss a show.”

The artist then shared the new date for the concert: “I will be rescheduling tonight’s show at Globe Life Field in Arlington, TX for Sunday November 26th of this year. All tickets will be honored, and it will be a phenomenal show."

“I hope to see you then, and again, am so deeply sorry for any inconvenience this has caused. It is never my intention,” she concluded the post. “Sending you all love x Pink.”

The Summer Carnival tour launched in Europe in early June and traveled to North America on July 28. In August, Pink reached a milestone on the tour in Milwaukee, as she became the first woman to headline a stadium in the state.

“It means the world to me. It is never lost on me. We aren’t the cool kids, Thank God. We’re just gritty, magnificent humans, doing our best,” Pink wrote in a statement on Instagram at the time. “Thank you for letting me in.”

Meanwhile, in February, the singer opened up in an interview with PEOPLE about her life as a rock-star mom.

"When I had kids, people said, 'Your career's going to be over. How are you going to tour?' " said the "Never Gonna Not Dance Again" hitmaker, who is mom to daughter Willow, 12, and son Jameson, 6, with husband Carey Hart.

She continued, "I did not know I was going to have a family. I didn't picture that for myself because I was terrified I would be a terrible mother. But, oh my God, being a mom is the most incredible thing I've ever done. It's shocking how responsible I've become."
