Trinny Woodall looks glamorous in a shimmering gold dress

Trinny Woodall put on a glamorous show when she attended the National Gallery for its annual summer party on Thursday night.

The TV star, 59, looked incredible in a sophisticated gold pleated halter neck that drew attention to her slim physique.

She increased her height in a pair of matching platform heels as she posed for photos outside the iconic London Museum.

Trinny opted for a flawless blush makeup look with a touch of nude lipstick, while her dark brown locks were styled in curls.

It comes after Trinny revealed she was left bruised and battered after crashing her car in LA last week.

She took to her Instagram on Friday and shared with followers an insight into her recovery.

Trinny was seen in white lingerie standing in front of her bathroom mirror, showing off her toned physique.

The makeup and fashion expert told followers she was suffering from a real sleep deprivation, as she admitted: “I haven’t felt hot in a while because that stupid little car accident in LA kind of knocked me out for six, must I and my arm is finally healing.’

She also told her followers live on her Instagram, “Still feeling a bit battered and bruised” after the incident.

MailOnline has reached out to Trinny’s representatives for further comment.

She later posted a story in her underwear when she revealed she was way too hot to stay clothed.

During her lunch break, Trinny took the opportunity to share with followers a glimpse of her supplement supplies stored in huge boxes.

She said, ‘I’m wearing my bra and pants because it’s hot. I have an hour lunch break and I’m figuring out what I’ve always wanted to do.

“Pain Medication, Allergy, Sleep, Sleep and Relaxation, Mood and Joint Mobility, Immunity, Ointments, Brain Omegas, Hair Supplements.” It has a lot of good supplements in it and you all ask me about things I take.’

It comes after her ex Charles Saatchi, 79, enjoyed a convivial lunch with Martha Sitwell, 43, at London eatery Scotts – a hangout where he previously took Trinny and his ex-wife Nigella Lawson, 63.

“He was chatting with Martha at his usual corner table. He still has it at 80,” an impressed fellow diner told Richard Eden of the Daily Mail.

Lady Sitwell confirmed, “Yes, we met for lunch,” telling Richard, “Charles is a very smart, very funny man.”

The former ‘face’ of Royal Ascot, she takes issue with her fellow diner’s use of the word ‘canoodling’, insisting: ‘We weren’t “cannoodling”; we made each other laugh.’

Charles reportedly divorced Trinny earlier this year, who made a name for herself giving style tips on the hit BBC show What Not To Wear before becoming a successful beauty entrepreneur.

The couple had been together for ten years.

Last month, Trinny fueled speculation that the relationship was over by revealing in an emotional post online that she had “moved on.”

The couple lived together in London. Sources close to the couple claimed the 20-year age difference was problematic, with Charles preferring quiet evenings, while Trinny preferred to be more social.

Nigella divorced him 10 years ago on the grounds of ‘unreasonable behaviour’ following an argument at Scott’s where he was seen to ‘tweak’ her nose and put his hands around her throat.

The household goddess, who was his third wife, reportedly did not seek any financial settlement, only asking to bring her cooking utensils.

Martha, the daughter of the late gastronome Justin de Blank, married film-producing Baron Sir George Sitwell in 2007 and they lived in his family’s £3.25 million Grade II listed home, Weston Hall in Northamptonshire.

She held a “divorce party” in 2017 to mark the end of their marriage.

She once described marriage in general as “pure misery,” explaining, “It sucks all the energy out of you, sucks your youth and all the fun out of your life.”

Elsewhere, makeup and beauty mogul Trinny said on Instagram last month that she was making progress following her split from Charles.

She posted, “It’s a new day, it’s a new dawn, it’s a new life.” She added, “I moved, but now I’ve moved.”

An emotional-sounding Trinny said, “I’ve spent the last 30 years of my life looking at this view. It’s the only consistent image I’ve ever had.’

“Recently with the big life change and move, it was important for me to come back here with (daughter) Lyla and family, just to have that moment, listen to the birds, be one with nature. Very healing.’
