Rylan Clark joined Claudia Winkleman and Tess Daly as he hit the DJ decks at the Londoner Hotel in Leicester Square on Tuesday night.
The presenter, 33, who revealed in January he has gained four stone after becoming 'dangerously thin' following his split from husband Dan Neal, appeared in high spirits as he helped the Strictly hosts unveil the No7 Pro Derm Scan.
Claudia, 50, looked effortlessly chic in a cream boucle jacket, while Tess, 53, opted for a stylish chiffon shirt and black trousers as they revealed the device for the brand, which diagnoses skin to offer a personalised skincare routine.
