But don't worry, our Lyds hasn't gone all diva on us. She was actually switching her look whilst filming new YouTube show Dating Dilemmas, which she co-presents with vlogger Jim Chapman.
Lydia first showed off her sweet side in a girly mint dress, complete with stand-out metallic courts.
Her second look saw her dressed to impress in a stunning off-the-shoulder frock from Virgos Lounge, paired with a ladylike updo.
And it wasn't long before Lyds donned her third outfit - and our favourite of the bunch - a stunning floral dress, £70, from the Rihanna for River Island collection.
Featuring a sexy dipped-hem and figure-skimming shape, this frock has summer glam written all over it. Plus just look at those pins!
Finally, the newly-brunette star wrapped things up in a lemon yellow skater dress and statement tribal necklace.
Now that's what we call an Instagram fashion show!
