And the lady herself celebrated this news in the only way she knew how.

By posting a picture of herself on Instagram in her pants.

We wouldn't have expected anything less from her.

The picture sees Rihanna seductively posing in a grey Nike t-shirt paired with a rather skimpy pair of black pants.

She accessorised the outfit with gold hoop earrings, a chunky gold chain and lashings of bright pink lipstick.

So in summary: your quintessential Rihanna picture.

Alongside the photo Rihanna wrote the caption: "Just do it!! Lol"

Lol indeed, although we're still not quite sure what it is Rihanna is lolling about.

The 'Diamonds' singer will be co-headlining the 20th T in the Park festival next year alongside Mumford and Sons.

The announcement was made today with tickets going on sale this Friday from 9am for the festival which will take place over the weekend of the12th- 14th July 2013.

Rihanna has also been confirmed as one of the four big name acts who will be performing at this weekend's X Factor final in Manchester.

She will be joined by Emeli Sande, One Direction and Kylie Minogue for the grand finale.

We anticipate another similar picture before, after and possibly during (you never know with Ri) her performance.
