A bikini-clad Rihanna goes for a dip in the Dead Sea ahead of her concert

Rihanna put her bikini to good use on Sunday as she went for a swim in the Dead Sea.

But there was nothing dearly departed about her behaviour as she laughed and splashed around in the salt lake which borders Jordan to the east and Israel and Palestine to the west.

Rihanna, 25, was taking a moment before she got ready to perform in Tel Aviv as part of her Diamonds World Tour.
But it wasn't all just fun and games, for a photographer was there to capture a few bikini shots of Rihanna, who was more natural than usual, as her long dark hair was pulled back into a simple bun.

Afterwards, she washed the salty water off under the public beach showers before heading back to her hotel in preparation for the night's gig.

Over the weekend, Rihanna made time to send a loving birthday message to Katy Perry, who celebrated her 29th birthday on October 25th.

Hopefully the Roar singer didn't mind her Bajan BFF's tardiness who tweeted a piture montage the following day.

Rhianna wrote: 'Happy Birthday to my lover and friend !! I miss you so much!! I love the phuck outta you!! I hope I could squeeze on you soon!! #KatyAnna @katyperry'.

The Diamonds singer clearly had so much love for Katy, but she may well not have read the comments made by Perry about the risqué behaviour of some of her female contemporaries.
