Berlin, Nov 24 (IANS): Even though singer Rihanna was busy with her 777 tour, she managed to attend ex-boyfriend Chris Brown's performance here.
The singer was promoting her latest album "Unapologetic" and made sure she marked her presence during the performance and even partied with him after the show.
"Rihanna was there for Chris's show and tried to keep a low profile but they went clubbing afterwards to celebrate it going well," dailystar.co.uk. quoted a source as saying.
Rihanna has denied any romantic link up with Brown. They dated each other for one year before ending their relationship in 2009.
