The gorgeous DJ, 32, shared a snap of herself at the gym on Sunday (28 December) and said: "Back on it."
Wearing a pink sports bra and a pair of leggins, Lauren's trim and toned waist was clear to see in the sultry gym selfie.
Yup, we totally look like Lauren right now too.

Lauren had been busy spending Christmas week playing board games with her family and, just 24 hours after her first workout, she decided to get on with another one!
On Monday (29 December) she took herself out for a run. Sharing a pic of her super cool trainers, Lauren added: "Time for a run in the winter sun."
We're totally exhausted just thinking about all of this exercise, so 10 out of 10 for effort Lauren!
