Yes, Rihanna Shares New Falcon Tattoo, Tweets from Ailing Grandmother's Bedside

As of Monday evening, Rihanna is in London, where she's reportedly working on a new fashion reality television series for the next several weeks. Hopefully she's had enough family time to last her through the summer.

Rihanna's been laying low the past couple of weeks, having postponed a trip to the UK in order to spend more time with her grandmother, Dolly Braithwaite, who is in a New York City hospital battling cancer. But the singer hasn't totally abandoned the spotlight: She's been very active on Twitter, where she posts intimate updates on her life for her nearly 21 million followers.

On Saturday, Rihanna posted a picture of her latest tattoo, an intricate falcon etched on her ankle. The singer shed light on her choice of ink via Instagram caption, writing, "Falcon: a light that shines in the darkness! Never close their eyes during sleep." The following day, the performer posted a series of pictures of herself with her grandmother with heartbreaking lines like, "My heart smiled and cried all at once." She also shared a rather silly photo of her granny sporting a TrukFit cap (courtesy Lil Wayne).
