Rih Rih shared her birthday glitz with her fans by uploading a number of pictures on Instagram and Twitter.  She began with a tweet saying "#epic day already, I woke up to sunshine in paradise and #STAY done jumped 54 spots to #3 on the BillboardHot100!!" She also posted a few pics of her and Brown together, one in which she is sitting on his lap wearing her bikini, shades and big hoop earrings. "#Pour it up pour it up! #birthdaybehavior," she wrote beneath in the caption.

Later on, the "Stay" singer continued her festivities with her family and friends.

Besides the fact that she is now a quarter century old, the Grammy Award-winner has other reasons to smile due to the fact that she just launched a major deal with British retailer River Island to debut her own fashion line and she landed a deal with MAC Cosmetics. Her collaboration with the makeup company includes different makeup items which will launch this year starting with "RiRi Woo," a lipstick inspired by her favorite MAC red lipstick Ruby Woo.

"When you think of makeup, the brand that pops into your mind -- for something legit -- is MAC," the singer told WWD.

"Whatever color you want, it's like 'Let's go to MAC.' I've been using MAC on tour for such a long time it was a natural fit for me. I have always loved makeup, and I always said that if I do it, I want to do it with a credible brand."
