Singer could be back on the dating scene
The actor attended a farewell bash thrown by the singer before she headed to the UK.
‘They were affectionate for everyone to see,’ a guest tells The New York Daily News.
‘From the moment he walked into her party, Rihanna lit up.’
Rihanna, 21, was apparently introduced to Tristan, 20, by a music producer they’ve both worked with.
She split from ex-boyfriend Chris Brown in March.
