Walking on water: Bar Refaeli started the day with a photoshoot, tweeting the picture of herself in a black bikini on the isle of Mykanos.

Dancing on my own: Another image showed the beauty shaking her blonde hair around, as luxury yachts floated past behind her.

Fresh faced: Bar shared this picture of herself soaking up the sun on the Greek isle.

Beautiful location: Bar is vacationing in Mykonos, tweeting this picture of the sunset yesterday.

It certainly looks like Bar Refaeli got out of the right side of bed this morning.

While most of us start the day reaching blearily for a coffee, the bright-eyed beauty stripped off for a bikini shoot.

'Good morning! I am walking on water today,' she tweeted. 'What r u doing?'

The early morning snap accompanying her tweet showcased model Bar's amazing figure, in a black bikini.

The 27-year-old appeared to be standing on a hidden walkway beneath the ocean, on the Greek isle of Mykonos.

Another image showed her kneeling, yachts in the background. She wrote 'dancing on my own'.

Bar has had to get used to dancing alone, since the break-up of her five-year relationship with Leonardo DiCaprio.

The Sports Illustrated model claimed in a recent interview with Maxim that she is seldom asked out by men.

She bemoaned: 'I think part of the reason [that I'm single] is that I’m not out much.

'I’m usually at a photoshoot or going to sleep early. I don’t really have a chance to meet people other than businessmen on planes.'

Bar added: 'Like, the other day, I was at the airport, and there was a cute guy who I saw notice me.

'But instead of coming up next to me, he put his head down and started texting to appear like, "Oh, didn't even see you!"'

When Fox signed the Israeli supermodel for $300,000 in 2008, the clothing line faced a potential consumer boycott as Bar avoided Israel's mandatory military service through a nuptial exemption.

Fox was forced to reassure the press that it encouraged enlistment into the Israel Defense Forces and opposed draft-dodging.

Bar also agreed to visit injured soldiers at the Sheba Medical Center in Tel Hashomer and made a public statement saying: 'From now I will collaborate with the IDF forum on all my visits to Israel.'
