She's weathered criticism for her inclusion in the Dancing With The Stars lineup.

But on Sunday evening, Erin McGregor totally killed it with her incredible, high-tempo routine. https://twitter.com/SenLynnRuane/status/952629211759566848 Notching up a 7, an 8, and a second 8 from the judges - to give her a total of 23 - Erin and her professional partner, Ryan McShane, definitely had oodles of sass.

On Saturday, Erin showed off nasty bruising on her leg on Instagram - admitting that her gruelling training routine was taking its toll. "I've trained til I’m black and blue!!" she wrote. "I can do no more! Confidence is the key." Erin previously admitted that her partner, Terry Kavanagh, is "holding it all together behind the scenes" while she takes part in the show. As she told the Sunday Independent: "Terry works nearly seven days. He has his week-day work - he’s a courier - but he’s also a singer and does MC-ing at fight nights. "I’ve had 16 months of maternity leave, so Terry has been holding the financial fort - and that’s the difference in my relationship now."
