The TV presenter will continue her position without her former best pal Phillip Schofield by her side.
Her return will be on Monday 4 September which coincides with the end of the summer holidays.
She has spent her time off with family and holidaying in Portugal but will be heading back into the studio.
Holly has been investigated as part of Schofield’s departure but a source said: “Holly has done everything that was asked of her during the investigation. She told them everything they asked and has done all she can to help when answering their questions. She’s got nothing to hide”.
