Radio host Jackie O joins Team Lob.

Zoe Foster Blake isn’t the only famous Aussie lady to take her short hair even shorter this summer.

Jackie O’s hair has been hovering around just-past-collarbone-length for a little while now, but she’s just dusted a few more centimetres off the ends this weekend – firmly landing her in ‘lob’ territory.

The radio co-host’s in good company there – every celebrity from Mindy Kaling to Rosie Huntington-Whiteley has joined the long bob mob over the past 12 months.

Jackie, 39, shared a photo of her gorgeous new shoulder-clearing cut on Instagram, writing, “I’ve gone shorter (again).”

The stylist responsible for the cut is none other than Renya Xydis of Valonz Hairdressers, who's performed a lot of the amazing hair transformations in our Chop series.

There's one thing we know for sure about 2015: the lob ain't going anywhere.
