Attending the premier of Eddie's latest movie, The Theory Of Everything, the couple couldn't stop smiling as they posed together.
And, with her ring sitting pretty on her finger, Hannah even gave us all a glimpse of her engagement sparkler!
Clutching onto her fiancé's arm, Hannah showed off her gorgeous rock in all its glory while wearing a floor-length purple gown for the occasion.
Keeping her look simple and understated, Hannah wore her hair in tousled waves, glitzing up her ensemble with an oversized gold statement ring.
Meanwhile, Eddie made sure to look dapper in a blue tartan-print suit and tie. Wearing a big smile on his face, the 32-year-old cosied up to his other half for the waiting photographers.
But, having his lovely fiancée on his arm wasn't the only reason Eddie was in good spirits.
After his impressive performance in the Stephen Hawking biopic, the actor has been given an Oscar nod for his portrayal of the famous theoretical physicist.
He stars alongside Felicity Jones, Harry Potter's David Thewlis and Boardwalk Empire star Charlie Cox in the film.
Eddie and Hannah's loved-up red carpet appearance comes after the pair announced they were engaged back in June.
After two years of dating, the Jupiter Ascending star proposed to his long-term girlfriend, and following their happy news, an announcement of their engagement was posted in The Times newspaper.
It read: The engagement is announced between Edward, son of Mr and Mrs Richard Redmayne of London, and Hannah, daughter of Mr Nicholas Bagshawe and Mrs Caryl Bagshawe, both of London."
