Myleene Klass looked in good spirits as she arrived for work at Smooth Radio on Sunday following ex Graham Quinn's friends branding her a 'vindictive bully'.
The radio presenter, 47, has found herself in the headlines after accusing her former husband of cheating on her with another celebrity, who she has refused to name, shortly before their 2011 wedding.
Graham's pals have hit back at the shock claims and told Daily Mail's Grant Tucker that the former Hear'Say bodyguard, who shares daughters Ava, 17, and Hero, 13, with Myleene was 'not going to dignify these fantasies with a response'.
They also believe it was especially 'vindictive and calculated' of the singer to launch the bombshell on what she would have known was the week of Graham's 51st birthday.
Despite the drama, Myleene flashed her gorgeous smile as she made her way through Leicester Square, London.
The TV personality put on a leggy display in a beige dress which she tied a black scarf around her waist and a Moschino belt.

She kept comfortable in a pair of black padded sandals and carried a coordinated handbag Chanel handbag.
Leaving her long locks loose, she accessorised with a pair of sunglasses and a simple gold necklace.
It comes after Myleene hinted at more revelations as she issued cryptic warning to those that 'have reason to' be afraid, after she made her explosive claims about her ex-husband.
After opening up about the scandal in an interview for Paul Brunson's We Need To Talk podcast, Myleene took to Instagram Stories to state she has 'receipts,' and 'won't keep her mouth shut.'
The post also included a snap of her MBE, after receiving the honour for her services to women's health, miscarriage awareness and charity last month.
While Myleene used the post to reflect on her recent acheivements, she also declared she's 'finally found her voice' after opening up about her cheating ordeal.
She wrote: 'Wow. What a week it's been! Firstly, thank you. I have quite literally tens of thousands of messages of love and support for me and my family. I took a long time to learn there's strength in vulnerability.
'In a varied week where my interview with @paulcbrunson and @needtotalk went viral and reached the people who needed to hear it, where I was part of the incredible @stjohn_ambulance team who helped to save a persons life and where my children and I somehow managed to rescue our passports from the bottom of the Adriatic, it's been a mixed bag!
All this to say, at 47, I've finally found my voice and it's clear, unapologetic and brutally honest.
To those that fear its truth, you probably have reason to; I have receipts. To those that need to hear it, I've got you and I fully intend to continue using it to change the laws and legislation that neglect women and children in this country and around the world.
Myleene then ended her post with a Bible quote that said: 'And the truth will set you free' John 8.32,' before adding her own words: 'And then some.'
The former One Show presenter left fans reeling when she dropped the explosive claim her that ex-husband cheated on her with a female celebrity in a very honest chat with Paul C Brunson.
Myleene said she walked in on the moment ex Graham Quinn and the woman were taking each other's clothes off on the balcony of her home.
Refusing to name the woman, Myleene hinted that the person in question has built a career off a 'family brand' and clarified that it was before they had got married.
As mystery continues to swirl around the celebrity in question, Myleene declared she doesn't regret her honesty in the interview.
She wrote on Instagram: ''You should do it, it would be good for you, but be honest, everyone knows when people aren't honest'.
'My manager before 'We need to talk podcast'.
'Errrrr s* Leens, I didn't think you were going to be THAT honest'. My manager AFTER 'We need to talk podcast'.
'I flew back from abroad to do this podcast. I'd heard a lot about @paulcbrunson and had seen the @needtotalk headlines. As I've gotten older, more comfortable with being vulnerable, I'm drawn to things that stretch and challenge me.
'I wasn't prepared for how disarming Paul is and how he looks into your soul and pulls out the very core of what makes you tick.
'I didn't think he'd be able to do it. From the outside, what do we have in common? Maybe that was the challenge, to see what he had on me. Turns out, a lot.

Myleene previously revealed she was 'sobbing in the bath' the night before her wedding to Graham, as she knew it 'wasn't right' between them.
The mother-of-two explained: 'I walked in on him with a famous person on my birthday on a balcony.'
According to the TV presenter, the pair tried to claim that it wasn't what it looked like and she continued: 'I'm in my house, it's my party. They weren’t having sex, but they were unzipping each other.'
Graham tried to blame the incident on being drunk and she admitted the whole ordeal was a 'pretty big red flag' but still went through with their wedding in October 2011.
Turning her thoughts towards the other woman, Myleene said: 'I've made peace with that situation now, but for a long time, it was very difficult to see their life.
'My life literally just broke apart very, very publicly and their life, they've managed to continue building a family brand on it. I have to take some accountability
'Look, you know, first and foremost to my children. My children have asked enough questions and it's never been a case of laying out my stall now.
'It's got to be as and when. But here's the funny thing - school mums, people who just want to gossip, will go to your children before anybody else.'
