Chris is currently on his 'Carpe Diem' tour and performed a gig in the German capital last night (22 November), which RiRi flew over to attend.
Even though she has just wrapped up her own whirlwind '777 tour' (that saw her put on seven concerts in seven countries in seven days), the 24-year-old Bajan singer doesn't seem to be taking any time off and jetted back over to Berlin to lend Chris some moral support during his show and then celebrate with him afterwards.
The former couple headed over to Adagio nightclub for the after-party, where Rihanna was seen downing shots and in good spirits. Does she ever sleep?!
Chris kept a low profile entering the venue, covering his head with a scarf. However, once inside he then basked in the spotlight and was caught smirking while having a cheeky cigarette.
The alcohol appeared to be in full flow and the pair danced and enjoyed themselves while spending their Thanksgiving in a much less conventional way than their family and friends back in America.
Rihanna recently spoke out about her rekindled friendship with Chris and claimed that they are not dating.
Nevertheless, it sounds like they were pretty cosy yesterday and, according to US website Just Jared, the 'Diamonds' star was even seen apparently heading back to her bad-boy ex's hotel after their night of clubbing!
