She landed the job as host of Love Island after Caroline Flack stepped down amid her assault charge. 

And Laura Whitmore was delighted after she filmed her first scenes for the winter edition of the show, as she shared a fun video via Instagram from Cape Town, South Africa, on Wednesday.

In the short clip, the presenter, 34, stepped into a room with her pal before dancing in delight and jumping onto her bed to the tune of Katrina and the Waves' hit song Walking on Sunshine.

Laura showed off her slender figure in a stylish black mini-dress that had a red polka-dot design for an extra glamorous flair. 

Her blonde locks were brushed into a sleek, straight style while she wore a natural palette of make-up for her day of filming. 

She used her electronic toothbrush as a microphone and busted out her best dance moves while pretending to sing along to the track.

Jumping down from the bed, Laura ran out of the room and showed off the clothing tags that were still attached to her outfit.
