Well, the rumours that he'd reunited with on/off flame Amanda Seyfried are clearly false.
'Mamma Mia!' star Dominic Cooper has been spotted having a whale of a time with a woman named as Ruth Negga.
She in a bikini and he in a small pair of swimming trunks, they had a passionate squeeze and relaxed by the pool with fellow actor Benjamin Walker.
Cooper started dating Seyfried following their appearance together in the ABBA musical in 2008.
They split in 2010 when he met 30-year-old Negga, but had reportedly been on and off every since - though the latter rumour was never confirmed.
Take a look at their holiday below.
