Holly Willoughby was left red-faced after Phil revealed to viewers what she did in the This Morning ad break.
As the next segment of the ITV show started Holly was seen in stitches by viewers, leaving Phil to apologise for her and explain.
Phil confessed the reason Holly was laughing was because she had been singing along to Our House by Madness - in a very deep voice and the adverts had finished earlier than she was expecting.
Phil then did a hilarious impression of Holly singing in a very deep voice - leaving the TV host embarrassed.
She said: "Stop it, stop it, that was for your ears only."
Despite her dodgy singing Holly's fans were very impressed with her outfit today, saying she'd finally found the colour that suits her best.
The This Morning host looked pretty in purple after opting to wear lilac, which complimented her blonde bob and sparkling blue eyes.
She then teamed the long-sleeved cashmere jumper, from Pure Collection - priced at £120 - with a tweed lilac skirt from Zara, costing £49.99.
And to finish her look she chose her signature nude heels from Giovanni Rossi.
*This Morning continues at 10:30am on ITV tomorrow
