Outnumbered actress Ramona Marquez looks completely different as she poses in bikini

OUTNUMBERED actress Ramona Marquez dazzled fans as she modelled a white halterneck bikini for a series of Instagram snaps.

The former child star, 22, who shot to fame on the hilarious BBC sitcom playing know-it-all child Karen Brockman, joined Outnumbered when she was just six.

Ramona played the youngest sibling in the Brockman family and later went on to study Mandarin and Spanish at the University of Manchester.

The actress looks very different now to how she did in her younger days - sporting an impressive selection of tattoos.

Ramona took to her Instagram page to showcase her plunging halterneck swimwear in a trio of snaps.

She masked her face with her phone yet her cropped brunette locks could be seen peeking into the shot.

Ramona accessorised with a diamante belly button stud, a Pandora bracelet and a daring manicure.

She referred to the new Barbie movie in her caption as she wrote: "Just Barbie things."

One fan was quick to react: "Pretty Barbie," as another put: "She’s everything."

A third then wrote: "Omg so gorgeous."

Last year, the star looked almost unrecognisable in a rare red carpet appearance.

Ramona played highly-critical tot Karen between 2007 and 2016.

She landed the role in the BBC sitcom when she was aged just six years old.

In 2009, Ramona became the first child to win the British Comedy Award for Best Female Comedy Newcomer.

She also starred as Imogen Pollock in the made-for-TV movie Enid which detailed the life of children’s author Enid Blyton.

The following year she starred as Princess Margaret in The King’s Speech alongside Colin Firth and Helena Bonham Carter.

In 2021, the child stars of Outnumbered reunited for the first time in forever - and they even documented it for fans.

Ramona and her former co-stars, Daniel Roche and Tyger Drew-Honey enjoyed a lunch date together.
