Russell Brand  donned a life vest this afternoon to take a jet ski out in Miami! He's down in Florida prepping for his singing and dancing role in Rock of Ages. The movie's director, Adam Shankman, has some of the stars like Julianne Hough and newcomer Malin Akerman in the Sunshine State perfecting their moves before the cameras start rolling during the early Summer. Russell's wife, Katy Perry , meanwhile, continues to travel the world on her Teenage Dream tour. Russell and Katy have been meeting up for the occasional rendezevous when their equally busy schedules allow — they had a particularly loved-up moment in London two weeks ago at the UK premiere of Arthur . She's in Australia at the moment, apparently longing for a traditional California Cinco de Mayo celebration between shows, though she was able to attend the launch of her fragrance, Purr, in Melbourne last Saturday and attended the city's Logie Awards Sunday. Katy also landed on the June cover of Vanity Fair , and spoke about deciding to finally show pictures from their wedding  during the Grammys in February. Katy said, "I felt the moment was right and not forced. Russell and I had time to savor our moment privately first and then share it with people when we were ready, and not for a paycheck. I loved the idea, because I thought it was beautiful and artistically accompanied the song I wrote for him. Plus, it was Valentine’s eve!"
