Elon Musk’s ex-wife Talulah Riley, 36, hitches up with Love Actually’s Thomas Brodie-Sangster

She has such allure that she married the world’s richest man not once, but twice. Now, Elon Musk’s willowy ex Talulah Riley is dating a baby-faced actor who doesn’t appear to have aged since he found fame at 13 in Love Actually.

Thomas Brodie-Sangster, now 31, is co-starring with the actress in Danny Boyle’s upcoming Sex Pistols drama, playing pop svengali Malcolm McLaren to her fashion designer Vivienne Westwood.

They began dating during filming over the summer and their relationship remained undetected until The Mail on Sunday learned that 36-year-old Talulah’s previous romance with Matthew Rice had come to an abrupt end.

‘Talulah and Matthew were on-off for a long time, but it seems that romance fell by the wayside to make room for Thomas,’ said a source. ‘Talulah was dating Matthew right up until the spring, and he’s still a little shocked and saddened it has all ended between them.’

Matthew confirmed the split when approached by this newspaper, saying: ‘She’s a wonderful and amazing girl, she’s utterly gorgeous. Whoever gets to be with her, whether famous or not, is a lucky man.

‘It’s such a pity it ended. I was so lucky to be in her attendance for a bit. It was on and off for a long time and it eventually ended without any arguments. We are still friends but we aren’t in regular touch any more.’

Diminutive Thomas’s star is in the ascendant since his acclaimed role in Netflix chess drama The Queen’s Gambit last year.

He is much younger than Talulah’s recent companions: ex-husband Elon is 50 and Matthew is 59. In February, the MoS revealed that she and Matthew had been quietly seeing each other in the wake of his 2018 divorce from ceramics designer Emma Bridgewater, to whom he was married for 30 years.

Emma and Matthew have four grown-up children together and started their pottery empire 36 years ago, before Talulah was born. Last night, Matthew laughed off any suggestion that his split from Talulah could make way for a rekindled romance with Emma, 61. He added: ‘I think the idea of me returning to Emma is very unlikely. That would be a terrific waste of everyone’s time.’

When asked about Talulah moving on to Mr Brodie-Sangster, Matthew said: ‘He’s a very lucky man. I haven’t got anyone at all on the scene now, but please do ask around for me. I am on the lookout.’

Talulah married PayPal and Tesla tycoon Musk in 2010, but they split two years later, before remarrying in 2013. The billionaire filed for divorce in 2014, then withdrew it. Two years later, Riley filed for a divorce which was finalised later that year.

At the time, Elon said: ‘We took some time apart for several months to see if absence makes the heart grow fonder, and unfortunately it did not.’
