Blake and Louise to step out at Cup Day

Controversial pair Blake Garvey and Louise Pillidge may make their first official public appearance as a new couple at the Melbourne Cup Carnival.

Garvey, who dumped fiancee Sam Frost then hooked up with Pillidge who placed third on Network Ten's The Bachelor, is on the guest list at the extravagant GH Mumm birdcage marquee for Cup Day - and he has a plus one.

Garvey will join last season's Bachelor Tim Robards and his partner Anna Heinrich in the Cote d'Azur themed marquee, as well as intentional Australian models Bambi Northwood-Blyth, Alexandra Agoston and Zac and Jordan Stenmark.

Guests in the lavish marque will enjoy expensive French champagne and caviar flown in from abroad 24-hours before it is served.

Garvey may also make an appearance at another marquee on Derby Day.

He and Pillidge announced their relationship to Australia via a gossip magazine and did an interview on Ten's The Project while on a romantic holiday in Thailand.

Second placed bachelorette Lisa Hyde also told The Project that after The Bachelor finale when Garvey proposed to Frost, he also contacted her asking if she could see a future with him.
