Britney Spears shared a cryptic message with her more than 42.2 million Instagram followers on Sunday, hours after reactivating her Instagram account.

Following a brief break from social media, which lasted under 24 hours, the pop star, 41, raised eyebrows by sharing a photo of a pink heart-shaped cake with ‘see you in Hell’ written in pink frosting.

While it is unclear exactly who she is addressing, the mother-of-two did insisted to fans on Friday that her bombshell memoir, The Woman in Me, was not intended to ruffle any feathers or hurt anyone’s feelings.

This marks her second post back after deleting her Instagram for less than a day.

Britney Spears shows off gorgeous dress that she made herself

On Saturday, the musician rejoined the platform as she shared a post in a white minidress.

‘CLASSIC !!! I made this dress, no lie !!! It snapped in the back when I started shooting, OF COURSE !!! I’ve waited three years to wear it … have no idea why ??? HMMMM,’ she captioned the post.

The video appears to have been recorded sometime last year as a light up Christmas tree was visible behind Britney for its duration.

The brief deactivation of her Instagram profile came amid bombshell revelations exposed in excerpts from her forthcoming tell-all.

In the book, Britney confessed to cheating on Justin with her choreographer Wade Robson.

The star also shared that she had an abortion at age 19 because Justin Timberlake ‘wasn’t ready to be a father.’

Extracts from Britney Spears’ upcoming leaked memoir

Shortly before nixing her Instagram page, she shared a lengthy note about the attention surrounding her book.

‘I don’t like the headlines I am reading,’ she wrote in black font against a stark white background.

‘My book’s purpose was not to offend anyone by any means,’ the note continued. ‘That was me then. That is in the past.’

‘Most of the book is from 20 years ago,’ she went on. ‘I have moved on and it’s a beautiful clean slate from here !!!’

The pop star added: ‘I am here to establish it that way for the rest of my entire life !!! Either way, that is the last of it and s*** happens !!!’

Spears penned that while she wanted the baby and ‘dreamed of having a family’ with Justin, who was also 19 at the time, he ultimately ‘wasn’t ready’ for the responsibilities of fatherhood.

In an excerpt published by People the songstress remembered: ‘It was a surprise, but for me, it wasn’t a tragedy. I loved Justin so much. I always expected us to have a family together one day. This would just be much earlier than I’d anticipated.

‘He said we weren’t ready to have a baby in our lives, that we were way too young. I’m sure people will hate me for this, but I agreed not to have the baby.

‘I don’t know if that was the right decision. If it had been left up to me alone, I never would have done it. And yet Justin was so sure that he didn’t want to be a father.’
