Rihanna flew back to Europe this week (beg19Nov12) after her whirlwind 777 Tour to spend America's Thanksgiving holiday (22Nov12) with her ex-boyfriend Chris Brown in Germany.

The Umbrella hitmaker played gigs in seven cities in seven days to promote her new album Unapologetic before wrapping up the gigs in New York on Tuesday night (20Nov12).

Rihanna's tour stopped in Berlin on Sunday (18Nov12), and she flew back to the German capital just days later to see her former boyfriend Brown perform there on Thursday (22Nov12).

The singer attended Brown's show at the O2 World Berlin and later joined him for an aftershow party at a nightclub. They were photographed getting into a car together after the bash.

Rihanna writes in a series of posts on Twitter.com, "All alone in my big ole (sic) jet!!! See u soon lover... Happy Thanksgiving everyone... Berlin. Carpe Diem (Brown's world tour)."

Brown and Rihanna split in 2009 following a violent altercation on the eve of the Grammy Awards which left the Kiss Kiss singer with an assault conviction. They have sparked rumours of a reconciliation in recent months by spending more time together.
