Britney Spears posted a video of herself dancing up a storm in Mexico on Wednesday night and used it as an opportunity to take aim at her younger sister Jamie Lynn Spears.

That same day, her ex Sam Asghari unfollowed her on Instagram, weeks after filing for divorce following a 14-month marriage.

In her new clip, 41-year-old popstar Britney could be seen working her best angles in a white dress and bikini.

She captioned her post: ‘In Mexico now! When your sister says “I love her to DEATH”… you learn to start living!’

Britney’s caption was seemingly in reference to a January interview 32-year-old Jamie gave to promote her Fox show Special Forces: World’s Toughest Test.

Actress Jamie said at the beginning of the year: ‘Growing up, my sister became famous — worldwide famous — when I was very young.

‘It just feels like every time I work really hard to get something on my own, it’s not really worth it.’

Jamie then noted: ‘I’m so proud of her, love her to death, but I don’t know. Sometimes I feel like I don’t really have anything for myself.’

Meanwhile, as of Wednesday, 29-year-old actor Sam no longer followed his ex Britney on Instagram.

At the time of writing, the world-famous hitmaker still follows Sam.

The former couple started dating in 2016 and walked down the aisle last summer, with Paris Hilton, Selena Gomez and Madonna just some of the huge names in attendance.

Following the news of the separation, Britney told fans she ‘couldn’t take the pain anymore’ but would remain strong in the face of adversity after her husband filed for divorce.

Documents – which were filed at a court in Los Angeles – cited ‘irreconcilable differences’ and also revealed that the couple separated almost three weeks before their split became public knowledge.
