Princess Charlene is in recovery after a recent operation in South Africa.

Monaco's princess on Friday underwent a four-hour procedure, a statement from the office of her husband Prince Albert II said, without giving further details.

The news came following growing suspicion as to why the princess had remained in South Africa for so long.

She'd previously undergone "multiple, complicated procedures after contracting a severe ear, nose and throat infection in May," as specified by her foundation. She also told Channel24 what a "trying" time it's been for her away from her family.
