The charming royal and his former Burberry model girlfriend, who tend to keep a low profile, were pictured swiftly leaving the Prince of Wales Theatre on Tuesday night.
Harry, 29, dressed casually in a white shirt and navy chinos, and slung his matching sweater over his shoulder as he walked a few steps behind his girlfriend.
Cressida looked effortlessly cool in skinny jeans, a navy top and a tartan patterned jacket. The daughter of Jeffrey Bonas and model Mary-Gaye Georgiana Lorna Curzon accessorised with thick banded rings and a long silver cross pendant necklace.
The young lovebirds are clearly making the most of their time together. Harry and Cressida's outing to watch the popular satirical play follows their date the previous evening.
The British royal and his girlfriend were spotted enjoying an intimate James Blunt gig at The Tabernacle in Notting Hill. At the low-key affair, Harry and Cressida once again tried not to cause a stir as they discreetly slipped in and out of the venue.
It is widely speculated that Harry's cousin Princess Eugenie introduced the lovebirds. Harry and Cressida's romance has developed over the year, with the couple seen out and about on dates since they were pictured in Verbier in February.
