The Celebrity Big Brother star, who can be seen in the fourth series of MTV's EOTB, shared a video from her car en route to London today, teasing she'll be performing at the event.
Sadly, Megan, who was looking a-mazing, didn't give any further details about her song choice but fingers crossed she posts a video online after the event, right?!
Megan may be better known for her appearances on Ex on the Beach and Celebrity Big Brother, music has always been a major passion of hers. She auditioned for Jess Wright's band LOLA in the first series of TOWIE and also auditioned for Britain's Got Talent and X Factor.
CBB fans heard her singing voice when the housemates had to take part in a house talent show and she chose to sing 'Angel' by Sarah McLachlan.
Megs also has her own YouTube channel where she describes herself as a country/pop singer.
