Rihanna made Chris Brown lick icing off her face to celebrate her 25th birthday.

The 'Stay' hitmaker saw in the milestone on Wednesday (20.02.13) by snuggling up to her on/off boyfriend - who is still on probation for assaulting her in 2009 - and she posted a series of pictures on her Instagram account, one of which with some of her birthday cake frosting all over her face.

She wrote: ''Put this #cake in ya face! I made him lick all this icing off! Lol (sic)''

Rihanna shared a number of intimate pictures of her and the 23-year-old rapper, including one where he is cuddling up to her with his face nestled in her neck, while the Bajan beauty has her hands wrapped around him. She captioned the image: ''Like #diamonds in the sky (sic)''

The singer went on to upload several other images of the couple snuggling up to each other as well as one of a brand new Goyard designer handbag, which appeared to be a lavish gift from the 'Beautiful People' hitmaker, and one of her special birthday cake, which was decorated with gold marijuana leaves.

The singer - who is known as Badgalriri on the social networking site - wrote: ''Got the #goyard and getting lei'd at the same damn time (sic)''

Rihanna had Chris by her side again as she blew out candles on her birthday cake at a party thought to be held in a private room at the couple's hotel in Hawaii.

Earlier in the day, the pair were spotted hand in hand on a romantic stroll on a Hawaiian beach, where they took in the sea view and whispered sweet nothings to each other.
