Lisa Armstrong's friend has sent a message to social media urging the star to get in contact with him.
Her former Deuce bandmate Craig Young tweeted Lisa on Wednesday and claimed he had tried texting her "a few times".
He wrote: "@lisaAmakeup please call me ASAP. I’ve tried texting a few times."
Lisa hasn't posted anything on Twitter since Saturday November 3.
But she was spotted out with Big Brother host Emma Willis and presenter Stephen Mulhern at a talent competition in London on Tuesday evening.
Meanwhile, on Friday, Lisa tagged Craig in a Twitter post after one of her followers posted a throwback snap of the pair during their Deuce days.
Lisa wrote: "Ah look at us @craigryoung," to which Craig replied: "Lol. We were babies. Xo hey check your WhatsApp! I need to talk to you about our visit. (sic)."
It comes after Lisa appeared in the Family Division of the High Court in London on Monday amid her divorce battle with ex Ant McPartlin.
There was absolutely no intent to disrespect the court.
The former couple - who confirmed their split earlier this year - have begun a divorce court fight over money.
A High Court judge was analysing issues relating to the division of assets.
Ant was not in court but was represented by lawyers and he was "told off" by the judge for not attending.
The Saturday Night Takeaway presenter was instead snapped taking the former couple’s Labrador Hurley for a walk.
Mr Justice Mostyn said McPartlin should have been present.
"Why is he not here?" Mr Justice Mostyn asked barrister Jonathan Southgate QC, who is leading McPartlin’s legal team.
"There isn’t one law for the famous and one for the rest of the community.
"The rules say he was supposed to be here – and that can be reported."
Mr Justice Mostyn added: "He has been told off."
The judge indicated that he might have excused McPartlin’s non-attendance had he been contacted in advance and given a reason for it.
Representatives for Ant later explained his absence, saying in a statement: "Ant was advised by his media barrister that he didn't need to attend court today.
"There was absolutely no intent to disrespect the court."
Ant announced the couple's separation in January, with Lisa filing for divorce after his new relationship with former PA Anne-Marie Corbett came to light.
