Their marriage troubles came into light last
In his first interview
The pair confirmed they would be divorcing in January this year.
Most recently Ant has been admitted to rehab again after being arrested on suspicion of drink driving.
Who is Lisa Armstrong?
Lisa was born on October 26, 1976 in Oxford.
She came from humble beginnings and won a place at the BRIT School in Croydon Surrey.
This is where she met Kelly O’Keefe – her future bandmade.
She started her career as a dancer, but in 1994 she joined the band Deuce.
In January 1994 the band released their debut single Call It Love, which reached number 11 in the UK charts.
Deuce released an additional three singles before splitting up in 1997.
Lisa met Ant at a pop concert at Newcastle City Hall in 1994.
The pair were both performing at the concert, she with Deuce, and he with Declan Donnelly in their band PJ & Duncan.
The couple dated for more than 10 years before Ant proposed while the two were holidaying in Dubai on April 26, 2005.
Ant and Lisa tied the knot on July 22, 2006 at Cliveden, a country house hotel in Taplow, Buckinghamshire.
After Lisa gave up being a pop-queen she decided to make her living being a make-up artist.
She started writing a beauty advice column for Cosmopolitan before going on to work for TV shows.
The talented make-up expert has worked on shows like This Morning, Pick Me, X Factor, Britain’s Got Talent and Saturday Night Takeaway.
She is head of makeup and hair for Strictly Come Dancing.
Ant and Lisa had been together for 23 years before announcing they would divorce.
“In response to the recent speculation in the media, Ant is very sad to announce that, after 11 years, he is ending his marriage to Lisa McPartlin”
A spokesman said in January: “In response to the recent speculation in the media, Ant is very sad to announce that, after 11 years, he is ending his marriage to Lisa McPartlin.
“Ant ask for privacy at this difficult time, for both himself, Lisa and their immediate families. No further statement will be made.”
The couple had been under immense pressure following Ant’s addiction to prescription medicine and substance abuse.
They don’t have children together, but have a brown Labrador called Hurley.
It has been reported that Lisa could be entitled to half of Ant’s wealth after the divorce.
This means Lisa would walk away with £31million, according to The Sun.
Did Ant McPartlin have any other relationships?
Not much is known about Ant’s dating history before Lisa – but were dating since he was 19-years-old.
However, before getting into a long-term relationship him and Dec were known for their chat-up lines and received a lot of female attention.
In an interview in 2000 Dec said: “Ant is partial to this one chat-up line.
“He’ll go up to a girl, lick his finger and run it down her top, then he’ll say: “Shall I help you get out of those wet clothes?”
Ant insisted that this approach was actually used by Dec, and that it was used to make girls laugh.
Ant used to date former Byker Grove star Nicola Bell in the early 90s.
Nicola, who is now married and a mum-of-one, revealed in 2017 that they still talk, and she gave him support through his stint in rehab last year.
Nicola played Debbie Dobson, and is also a make-up artist after working as a flight attendant.
