Both women are currently at the celebrity-favourite Juice Master retreat in Portugal, founded by Jason Vale, which sees guests drink four juices daily rather than eating solid meals, while taking part in yoga, fitness, meditation, games and walks.

Their Thursday morning sweat session saw Alex working out in black crop top, posing in the mirror and writing: "Carol Vorderman, where's my gym buddy?"

Alex joked that she'd finished her workout, while Carol had only just arrived, but that's not to say Carol had been lounging in bed – in fact, she's been going for 5am yoga sessions and swims the whole time she's been at the retreat.
