Aubrey Anderson-Emmons stunned Channel Seven viewers on Friday morning when she looked almost unrecognisable during a TV interview.
The actress, 18, first won hearts as Lily Tucker-Pritchett on the long-running US comedy series Modern Family.
But she had fans doing a double take on The Morning Show when she looked all grown up, rocking a brand new look following her days on the cult hit.
The child star sported long curly locks and a trendy fringe which covered much of her recognisable face as she discussed her latest career move.
Releasing her new solo EP, Drown, Aubrey also reminisced over her time 'growing up' on Modern Family.
Making her TV debut on the show at age four in 2009, Aubrey said her 10 years filming the series was 'wonderful'.
'All the adults around me were supportive and lovely,' she continued.
Aubrey also revealed she had recently spent time re-watching the show because she could not remember filming certain episodes, as she was so young.
Elsewhere in the chat, Aubrey revealed the real reason she chose to use Frances Anderson as a stage name for her music career.
'People know me as [the character of] Lily, so I just wanted to start afresh,' she confessed.
However, she also explained Frances Anderson is part of her legal name and she wanted to shorten it.
'I have a very long name -- Aubrey Frances Anderson-Emmons,' she said with a laugh.
During the chat, Aubrey said she had always loved music.
'My mum is a musician and a classically trained singer, and my grandpa's also a piano player and a singer. So I guess it kind of runs in the family.'
She said her new music was partly inspired by her 11 seasons on Modern Family as well as 'what happened after' the show ended in 2020.
Her EP Drown comes after her well-received first single, the electropop song Telephones and Traffic, which dropped in May.
During its run, Modern Family won 22 Emmys and was a critics' darling and a ratings hit.
Aubrey's Lily, who in the show is the adopted daughter of Mitchell Pritchett and Cameron Tucker, became a fan favourite for her unfiltered and hilarious outbursts.
