The GMB presenter will be taking the reins as the programme kicks off at 8.30am, legging it from the Good Morning Britain studio next door as soon as he comes off air.
Piers has a few surprises up his sleeve for the veteran journalist, including a ‘This is Your Life’ style tribute to the Queen of Daytime Television called ‘Trip Down Memory Lorraine’.
He said: “To survive 35 years at the top of television is an extraordinary feat. “Lorraine’s a lovely lady and brilliant broadcaster…I look forward to sharing her big celebration in some way that makes her yelp in horror!”
What has Piers got up his sleeve?
The programme will be packed with other special moments and will include newly created opening credits, celebrity tributes, a look at some of her most daring fashion moments, along with a montage of highlights from her TV career.
Lorraine editor Victoria Kennedy has said: “As the show is a surprise, Lorraine doesn’t know quite what to expect.
“But I can promise we will have some poignant moments and funny clips as well as some familiar faces to help mark the occasion. It’s live TV so anything can happen, especially with Piers in our studio.”
Lorraine has shared her trepidation for the live show, posting on her social media that she has “no idea what is going to happen”.
The presenter has certainly changed a lot since appearing on GMTV 35 years ago, and has had a number of iconic moments on TV.
Some of these include her dressing up as Wonderwoman, interviewing Oprah Winfrey, and accidentally suffering a wardrobe malfunction while chatting to the Spice Girls.
The special episode of Lorraine is on ITV on September 30 at 8.30am.
