However, the couple haven't been seen together since they officially announced their relationship, until now.
The pair were spotted together on Wednesday evening while on a date to see a play in London’s West End, as seen in a photo obtained by The Sun.
Harry is said to be “besotted” with the 35-year-old actress, who is best known for playing Rachel Zane in Suits.
The two have been committed for about three months, and have previously displayed their commitment by wearing matching bracelets.
