Royal watchers have been speculating whether heavily pregnant Tatiana Santo Domingo will join the rest of the Monegasque royal family at the Monaco Rose Ball on Saturday night. Mum-to-be Tatiana is thought be very near to her due date, meaning that she may have to miss this year's soirée.
HELLO!'s sister publication HOLA! reports that Tatiana will welcome her second child in the next "five or ten days", leading fans of the 31-year-old heiress to conclude that she will most likely bow out of attending the Rose Ball.
If Tatiana does make an appearance, however, it will probably be her last engagement before she becomes a mother-of-two.
Heavily pregnant Tatiana may not be able to attend Monaco's Rose Ball
Swtizerland-born Tatiana, whose husband Andrea Casiraghi is Prince Albert of Monaco's nephew, has made few public appearances since it was confirmed in November 2014 that she was expecting again.
In January, six months into her pregnancy, Tatiana stepped out at Paris fashion week, attending shows by Valentino, Christian Dior and jewellery designer Sabine Ghanem.
The boho beauty dressed her baby bump in numerous stylish and quirky outfits including in an olive green dress and a vibrant orange patterned cardigan and black top and trousers under an emerald velvet jacket.

At the beginning of the month Tatiana showed off her rounded tummy in an Instagram photo posted by the ethical clothing company Muzungu Sisters which she runs with her friend Dana Alikhani.
"It's all about the bump today at Muzungu Sisters HQ," read the photo's caption. "Shooting for @nineinthemirror."
Tatiana and her long-time love Andrea, who tied the knot in on 31 August 2013 after eight years of dating, became parents for the first time five months before they wed.
Their firstborn, Alexandre, who is known as Sacha, turned two on 21 March, meaning that the couple will soon have their hands full with two babies under three.

It was recently revealed that Tatiana, who was educated at Le Rosey, had landed herself a spot on the 2015 World's Billionaires list as compiled by Forbes.
With an estimated net worth of £1.4billion, most of which the publication reported was from the inheritance from her grandfather's beer business, Tatiana was ranked the 847th richest person in the world.
