She has joined the likes of This Morning host Josie Gibson, GB News presenter and ex-politician Nigel Farage, food critic Grace Dent and JLS member Marvin Humes.
Out of this year’s line-up Jamie Lynn is perhaps the most famous for being the younger sister of pop star Britney Spears.
Jamie Lynn was born on April 4, 1991 in McComb, Mississippi, United States which makes her 32-years-old.
In contrast, Britney was born on December 2, 1981 and is 41-years-old but will be celebrating her 42nd birthday soon.
There’s a 10-year age-gap between the two sisters.
Meanwhile, their older Bryan Spears born on April 19, 1977 and aged 46 with an even bigger age-gap between Jamie Lynn and Bryan.
Many fans have already taken to social media to comment on Jamie Lynn’s age with many startled when they discover how old she was.
One user called @PinkFluffyChic posted on X, formerly Twitter: “Honestly thought Jamie Lynn Spears was in her mid 40s, not 32! #ImACeleb.”
While a second @scarsonbabylon remarked on the platform: “Jamie Lynn Spears is ONLY 32????”
A third named @ahend__x wrote: “How is Jamie Lynn only 32 #ImACeleb.”
Another @bdly25 said: “Jamie Lynn Spears is only 32 #imaceleb.”
One viewer @Margjacquieline posted: “Nah my mum is ripppinngggg into Jamie lynn “HOW IS SHE ONLY 32” Brev im tellin [sic].”
The viewer reaction comes as Jamie Lynn appeared to be struggling to add up 62 plus 32, leaving other fans in hysterics.
Her sister Britney also seemed to be subtly throwing shade at the mathematical faux pas with a post on Instagram featuring a chalk board with the irrational number Pi on it.
There was no caption on the image with Britney keeping the comments firmly turned off and allowing fans to speculate what the meaning could be behind the cryptic post.
Moreover, Jamie Lynn finally broke her silence about her famous sister, who described her as a “total b****” in her recent memoir The Woman In Me.
Jamie Lynn also shared heartbreaking details after she fell pregnant as a teenager.
