Pregnant Fearne Cotton displays a hint of baby bump in a tie dye dress as she enjoys night out with best pal Holly Willoughby

They've been friends for over fifteen years after first meeting as budding children's TV presenters.

And Fearne Cotton and her BFF Holly Willoughby proved their friendship is still rock solid as they attended the annual ITV summer party together on Thursday evening.

Pregnant Fearne, who is expecting her second child with her husband Jesse Wood, opted for a colourful frock while Holly went the opposite direction by donning a sombre black dress for the event held in London's Notting Hill.

The 33-year-old radio presenter showed off just a hint of her baby bump in a bright tie-dye smock dress.

Fearne accessorised her eclectic outfit with a pair of sparkling blue peep-toe heels and a purple satchel, styling her hair in low-slung bunches for a playful vibe.

Meanwhile, Holly opted for grown-up glam in a black lace dress with a low-cut neckline.

The 34-year-old This Morning host, who is currently on maternity leave after welcoming her third child with her husband Dan Baldwin, added a pair of simple stilettos and a chic handbag.

Fearne recently opened up about her friendship with Holly, declaring that she's always idolised her Celebrity Juice co-star because she's so perfect in every way.

'My aim in life is to be grown up like Holly. I go round there and her house is so perfect and she's so together and I go home and I think I live in a s**t hole', she joked to Red magazine.

The former BBC Radio 1 star also admitted she found it hard coming off maternity leave after giving birth to two-year-old son Rex.

She added: 'I still find it hard. I don't know any working mum who says, "I'm 100% happy leaving my kid".'

The stars were joined at the bash by ITV regulars including Amanda Holden, Alesha Dixon and Melanie Sykes.
