Singer Britney Spears says "of course" she will perform again as she and beau Sam Asghari go shopping.

Britney recently spent a month at a mental health treatment facility, months after she cancelled a Las Vegas residency following a health emergency suffered by her father and conservator, Jamie Spears. 

Earlier this week, her manager Larry Rudolph told TMZ: "I don't want her to work again 'till she's ready, physically, mentally and passionately. If that time never comes again it will never come again." 

His comments sparked alarm among Britney's fans.

On Friday afternoon, Britney and Asghari went on a shopping trip here. Paparazzi descended upon the couple, who were accompanied by a bodyguard. Britney appeared in high spirits, reports eonline.com.

"Britney, a lot of people don't think you're going to perform again," one photographer told her, as seen in a video. "Aw," she replied.

"Are we gonna see you perform again, Brit?" he continued.

"Of course," she said with a smile.

She also said she wanted to tell her fans, "I love you guys".

Amid her turmoil, there has been growing concern among fans over Britney's mental health and many calls to end her father's conservatorship, which a judge signed off on 11 years ago, after the singer's public meltdown. 

Many of her supporters are calling to let her get back control of her financial and medical affairs, in other words, "#FreeBritney".

Last week, Britney, her father and her mother Lynne Spears appeared at a court to discuss her conservatorship. A judge then ordered a court investigator's report on it, due in September.
