The jilted former French First Lady jetted to the sun-drenched isle to relax with friends as her ex-partner prepared to fly to freezing Washington to meet the Obamas tomorrow - his first state visit without her.
It is just under a month since the 48-year-old journalist spent eight days in a Paris hospital with extreme stress after a glossy magazine revealed Hollande, 59, was cheating on her with actress Julie Gayet, 41.
The scandal broke when photographs published in Closer showed the portly Socialist visiting a Paris love nest on a moped and wearing a crash helmet as a disguise.
Following the disclosure, Miss Trierweilerspent eight days in hospital suffering from the extreme stress at finding out her partner was having an affair.
But Miss Trierweiler made no attempt to disguise herself today as she lazed on the beach, shopped at a local market and chatted to girlfriends - French-Moroccan actress Saida Jawad and journalist Valérie de Senneville - on the palm-fringed island in the Indian Ocean.
Interestingly, one of her friends, Valérie de Senneville, is married to Michel Sapin, Minister of Labour, Employment and Social Affairs in Francois Hollande's cabinet.
Meanwhile, French President Francois Hollande is set to arrive in America tomorrow for a state visit hosted by the Obamas.
But breaking with protocol, it is believed he will attend a grand reception and state dinner held in his honour alone, following his high profile split from longtime partner Valerie Trierweiler.
It is believed the White House has now destroyed hundreds of embossed invitations to the event, because they included a reference to his now former partner.
