Princess Charleneof Monaco’s upcoming birthday celebration on Monday can be best described as royally intimate.

The South African-raised royal will turn 43 with only a handful of well-wishers on hand.

“She doesn’t like big celebrations,” husbandPrince Alberttells PEOPLE exclusively, revealing that this year’s party “is going to be pretty much a family affair.”

Having his family be an example of social distancing and other COVID-19 restrictions is important to Albert. The ongoing pandemic also changed the typical big birthday plans around the couple’stwins' birthday last month. Prince Jacques and Princess Gabriella turned 6 on Dec. 10.

“We can’t have big gatherings because we’re restricted even in private situations,” Albert, 62, adds. “We can’t be more than six.”

Theprince battled coronaviruslast spring and recently shared the longterm effects he experienced.

“There were times during the day when it just hit, but not like the kind of drowsiness you feel after a heavy meal. It was really just an experience of physical fatigue, like the kind that comes on when you’ve done too much or when you’re coming off an illness,” he told PEOPLE in December. “This virus stays with you quite a while.”
