She has been on cloud nine ever since the birth of her son Andreas last September. 

But Amy Jackson took an afternoon of mum duties to attend the International Women’s Day Caring Foundation fundraiser in London on Sunday.

The Supergirl star, 27, oozed sophistication in an elegant blue and red checked suit as she posed while leaving the star-studded event.

She showed off her svelte frame in the tweed number, which she wore a white crop-top underneath, flashing her honed waist.

Amy slicked back her long brown tresses into a high ponytail and kept her makeup natural and bronzed with a dab of pink lipgloss.

She accessorised her look with a white Dior saddlebag and a pair of pointed white court shoes. 

She kept the bling to a minimum with just a pair of dainty pearl studs, a silver Cartier bracelet and a silver watch.

A number of well-heeled guests had turned out in force at the philanthropic event, with jewellery designer Sabine Getty, royal confidante Astrid Harbord and British actress Amy Jackson all in attendance.

Rita Ora’s outing at the event follows reports that she and her boyfriend Rafferty Law, 23, have recently drifted apart. 

They began dating in December while working together on the Oliver Twist remake Twist, later going public at the British Fashion Awards.

A source told The Sun: ‘They grew close while they were both working in London, although they were just taking each day as it came and weren’t in a rush to label anything or move too quickly.

‘But Rita has spent so long out of the country now and they’re not talking as much as they were, let alone doing the things couples do when they’re together.’

The insider added: ‘Things are on ice until they’re back in the same country. They might pick up again then, but at the moment they are more like friends.’
