He kept a close eye on her all day while she sunned herself on her luxury cruise liner off Taormina, Italy.

And it seems that Scarlett Johansson’s bodyguard is never off duty for a second.

The actress’s burly sidekick was on hand with the soap as she hosed herself down after a dip in the water.

Clearly he takes his job very seriously.

Scarlett, 27, showed off her jaw-dropping curves as she washed herself after a dip in the water, appearing unselfconscious and very comfortable in his company.

The pair were joined briefly by a couple of crew members, but were alone for the majority of the time.

The actress was seen languishing on the boat alongside her bodyguard with whom she put on a very tactile display as she sunbathed earlier in the day.

And her bodyguard clearly not wanting to be left out wore some rather form-fitting black trunks as he kept a watchful eye on her.

Quite what he was expecting to encounter while at sea is anybody’s guess. But as they lay side by side on the deck, there was little space for anyone to get in between them.

Laying out on a towel on the front deck of the vessel, Scarlett was the centre of attention in her white Bond-style two-piece.

The Avengers star shielded her face from the sun with a visor and wore sunglasses over her eyes.

The actress was joined by her hunky bodyguard and two female friends, and the group kept hydrated by sipping from water bottles.

As they sped out to sea, the foursome snapped away with their cameras, taking in the breathtaking views.

Avengers Assemble became the third highest grossing movie in history by taking £936million at the box office, and Scarlett is seen as an integral part of its success.

A source told The Sun newspaper: ‘Scarlett is the hottest star in Hollywood and her inclusion in the sequel is a must.

‘Producers think that as the only lead woman in the film male fans have found her a key ingredient — both for sex and story appeal. She is loved by critics too.’

Scarlett is the only female member of the Avengers, and she revealed earlier this year how her character can more than measure up to her teammates.

She said: ‘The other day we were doing this big reveal shot of all the Avengers. Thor has got his hammer, Cap’s got his shield, Hawkeye has his bow and arrow, and Hulk is huge. Then it pans over to me and I’ve got guns.

Bohemian: The star wore a pretty white and purple sarong over her bikini

‘Iron Man’s like, hovering above all of us, ready to go… I was like, ”Joss… um… do I look OK holding these guns?” and he responded, ”She’s a total bad-ass. She’s a killing machine”.’

Scarlett has already appeared in Iron Man 2, but she is also due to star in Hancock 2 and Nick Fury.

Iron Man star Robert Downey Jr, and Thor actor Chris Hemsworth are also reported to have been offered 50 per cent pay rises for the sequel.
