Rihanna: Tini-Bikini in Barbados

Soaking up the sun, Rihanna chilled with a few of her pals on the beaches of Barbados on Wednesday (November 6).

The Te Amo singer rocked a tiny bikini that showed off her slim figure just one day after she celebrated her grandfathers 85th birthday.

During the bday party, RiRi tweeted a photo of her and gramps with the caption, Threw Bravo a birthday ba$h at mama Fenty crib!! #85blessed yearz! Many more to you Grandfadda!

Meanwhile, the busy singer is also getting ready to release her brand new MAC Cosmetics line and amped up excitement by sharing a sneak peek of the line on Tuesday.

With the pic, she wrote, #VIVAGLAM @MACcosmetics #RIRIheartsMAC#January2014 !!! We really worked to make this one of a kind for VivaGlam, right down to the packaging, which has never been done! So shoutout [email protected] and #ViViaGlam for going all the way with this!!
