The Emirates Melbourne Cup just got a genuine lift in the celebrity stakes with Rose Byrne announced as a special guest in the Lexus Design Pavilion. The babein’ homegrown Bridesmaids, Get Him To The Greek and X-Men First Class actress will add some sparkle to a distinctly tepid Cup guest list which includes Mischa Barton , Delta Goodrem and Brynne and Geoffrey Edelsten.

Byrne, who’ll be fighting it out with Katut and Rhonda for our undivided attention, is suitably chuffed at the prospect of all-you-can-eat horderves and bottomless bubbly.

I am thrilled to be attending this year’s Melbourne Cup as a guest of Lexus. I’m delighted to be back Australia for the Spring Racing Carnival, and I am looking forward to the trackside style and generous hospitality of the Lexus Design Pavilion

I’m yet to finalise my Cup plans Rose, so if you need a date for the day, you know where to find me. Just saying…

Organisers are hoping Byrne’s horse comes in because that girl’s developed a mean temper and can cuss like a sailor!
