The presenter has been absent from the ITV daytime show over the last seven weeks due to her annual summer break.
Holly will continue to present alongside other members of the on-air This Morning team, including Alison and the show’s other regular Friday co-host Dermot O’Leary, as well as the likes of Josie Gibson and Craig Doyle.
Former host Phillip left This Morning after 21 years back in May, amid reports of a fallout with Holly.
He later quit ITV altogether after admitting to having lied about an affair with a younger male colleague.
Following this, the programme also faced accusations of bullying and being a “toxic” workplace – something which bosses were swift to deny.
This Morning airs weekdays at 10am on ITV1.
