It is thought Lily gave up drinking around the time she started dating her Stranger Things boyfriend David Harbour, 45.
The couple were first spotted at the theatre in London last August and their relationship has gone on from strength-to-strength.
The mother-of-two previously took to Instagram to laud her new healthier lifestyle after she quit drinking.
She told her fans: '9 months sober today! And the beginning of an ab is appearing. Very pleased!'

Lily revealed she had turned to the bottle when experiencing trouble in her personal life in an interview with Stereogum in 2018.
Lily, who has bi-polar disorder, said: 'I think I’m a raging co-dependent and then when I feel like I can’t cope, I abuse alcohol and drugs to plaster over some stuff, but I’ve never been somebody that craves a fix.'
The Smile hitmaker also previously discussed her year of turmoil in 2013, taking place just months after she gave birth to her second child.

Lily admitted she was 'skidding from festival to festival', drowning her sorrows.
She credited her then-husband Sam Cooper from pulling her out of the dark place in her life, and revealed her depression stemmed from the luke-warm reception her music had been receiving.
Speaking candidly in an interview, Lily reflected: 'Summer '13 was a disaster. In short, I was a drunk mess.
'I was self-medicating with alcohol and whatever else and Sam was obviously attracted to me when I was like that,' she told the Sunday Times.

'He could see that I was being quite self-destructive and at one point he said, 'What are you doing? I would really like to be with you, but I can't be with you if you are going to be like this all the time.'
Lily separated from husband Sam Cooper in 2015 after about four years marriage.
The former couple announced they finalised their divorce in 2018.
They each share joint custody of their two children: daughters Ethel, eight, and Marnie, seven.
