Kate Middleton was out of the spotlight on June 1 as her husband, Prince William, and Prince Harry went out to a club in London.

The two spent the evening at Tonteria Club on Sloane Square and Prince William, who tried to hide his face under a bright orange hat, was seen with a friend leaving early Sunday morning, according to Entertainmentwise.

Tonteria, a Mexian tapas & cocktail bar, retweeted a message from a follower, reading:

Middleton’s is due to give birth in a few weeks and she was resting at home while the men went out to party. The duchess also missed out on Prince William’s polo match on Wednesday, reportedly resting at home as the duke brought the team the victory. Although she attended the event last year with her puppy Lupo, Middleton is taking good care not to overdo her activites before the birth of the royal baby.

The duchess will make a final public appearance before she is due to give birth, where she will name a cruise ship in Southamption on June 13. A spokesperson from St. James Palace said Middleton will take maternity leave after the birth of her baby, but it is not confirmed how long she will remain out of the spotlight.
