She is currently embroiled in a decidedly acrimonious divorce battle with estranged husband Ant McPartlin.
And Lisa Armstrong, 42, has sparked concern elsewhere in her private life, after her best pal and former Deuce bandmate Craig Young, 42, sent her an urgent message over Twitter, following multiple failed attempts to contact her over the phone.
Craig, who has been based in Los Angeles for several years, wrote on the micro-blogging site on Wednesday: ‘@lisaAmakeup please call me ASAP. I’ve tried texting a few times..’

Lisa, who last tweeted on Saturday, tagged her longtime pal Craig in a post on Friday, after one of her followers shared a throwback shot of the former singers together during their heyday in the pop group Deuce, which disbanded in 1997.
‘Ah look at us @craigryoung,’ wrote Lisa, prompting her friend to respond: ‘Lol. We were babies. Xo hey check your WhatsApp! I need to talk to you about our visit.’
However, while her friend apparently struggles to contact her, Lisa appears to be putting her marital woes behind her, as she was spotted looking chic as she judged the Rising Star talent competition at Under the Bridge in London on Tuesday night.

The makeup guru was joined by presenter Emma Willis, 42, and Stephen Mulhern, 41, as she stood confidently on stage at the packed out music venue.
Clad in skin-tight jeans and an oversized funnel-neck jumper featuring eye-catching pleated sleeves, Lisa looked self-assured and completely at ease under the stage lights.
Her platinum locks were styled into a sleek blunt bob with a central braid keeping her hair back off her face, and accessorised with a pair of hoop earrings.
The blonde beauty enhanced her natural beauty with lashings of mascara and perfectly sculpted brows.
Delighted audience members took to social media to share photographs of the night, with one cosying up to The Strictly Come Dancing make-up artist for a cute selfie.

Lisa’s outing comes as Hurley – the energetic brown Labrador frequently seen on separate outings with warring couple Ant McPartlin and Lisa Armstrong – is understood to be one of the key issues in their hefty divorce settlement.
Troubled presenter Ant, 42, could lose an estimated £31million after ending his 12-year marriage to the TV make-up artist, but is said to be reluctant to part ways with their pet dog Hurley.
The television star is understood to have credited the Labrador with helping him through his well-documented struggles with alcohol and substance abuse issues, with Hurley event given allowance to visit him as he tackled his problems at a residential rehabilitation centre.

The dog, who has been with Ant and Lisa since 2013, even accompanied the star during Britain’s Got Talent auditions at the London Palladium during annual Bring Your Dog to Work Day in February.
The presenter’s attachment to Hurley is said to be so strong that he even received birthday cards filled with the dog’s paw prints during his month long stays in Australia for I’m A Celebrity… Get Me Out Of Here!
As Ant moves on with new girlfriend Anne-Marie Corbett, faithful Hurley has been pictured with the couple during various strolls close to their west London home.
