Sister Catharine, who is also an actress, chose an asymmetrical swimsuit in a matching print, with cut outs and tie detail at the waist.

With her hair, longer than her sisters, falling in a relaxed style she too opted for no make-up for a day of fun.

The ladies took to the water and paddled along on their individual boards, first on their knees before later climbing to their feet.

This comes after Alexandra threw her support behind Sava Jeffries’s casting as Annabeth Chase in Disney Plus‘ Percy Jackson TV series, after several hateful comments surfaced online.

The star, who originally played the role in the 2010 movie Percy Jackson and the Olympians: The Lightning Thief and 2013’s Percy Jackson: Sea of Monsters.

Some fans were upset that 12-year-old’s casting because she is a Black actress and does not ‘match’ the character, since she was written as white in the original books by Rick Riordan, but both Daddario and Riordan came to her defence.

The It’s Always Sunny In Philedelphia star took to Twitter on Tuesday with a simple and supportive message for the young actress: ‘Leah Jeffries is going to be an incredible Annabeth!!!’

The news was announced on Thursday alongside 16-year-old Aryan Simhadri as Grover, weeks after Walker Scobell (The Adam Project) was announced as the new Percy Jackson.

Logan Lerman played Percy Jackson in the films, alongside Alexandra and Brandon T. Jackson as Grover, though fans were upset about the casting.

 The actor took to his official website on Tuesday to issue a passionate defense of youngsters casting.

‘This post is specifically for those who have a problem with the casting of Leah Jeffries as Annabeth Chase,’ he began.

‘It’s a shame such posts need to be written, but they do. First, let me be clear I am speaking here only for myself. These thoughts are mine alone. They do not necessarily reflect or represent the opinions of any part of Disney, the TV show, the production team, or the Jeffries family,’ he clarified.

‘The response to the casting of Leah has been overwhelmingly positive and joyous, as it should be. Leah brings so much energy and enthusiasm to this role, so much of Annabeth’s strength,’ he added.

He continued that Jeffries, ‘will be a role model for new generations of girls who will see in her the kind of hero they want to be.’

‘If you have a problem with this casting, however, take it up with me. You have no one else to blame,’ he continued.

‘Whatever else you take from this post, we should be able to agree that bullying and harassing a child online is inexcusably wrong,’ he said.

‘As strong as Leah is, as much as we have discussed the potential for this kind of reaction and the intense pressure this role will bring, the negative comments she has received online are out of line. They need to stop. Now,’ he stated.

It’s unclear when production will start on the Percy Jackson series quite yet, or what other characters from the books will be cast.  

Annabeth previously played Lola on Fox’s Empire and Brandi on Rel, with the film Beast with Idris Elba and Sharlto Copley in post-production.
