Kiernan Shipka attended a screening for her new Netflix movie Sweethearts in Los Angeles on Monday.

The Mad Men alum bared her long, toned legs in a strapless black mini dress with bow accents and matching opera gloves.

It comes after the actress revealed she had a ‘mental breakdown’ over turning 25 ahead of her November 10 birthday.

During an appearance on The Drew Barrymore Show, she said: ‘I was freaking out before. I would quite literally just be going about my day and then sort of descend into some sort of mental breakdown, which happens.

‘I’d be freaking out about a random thing and then I’d go, ‘And I’m turning 25 too!’ Like it would just happen, it would just come over me.’

But when the day rolled around, she said she felt ‘great.’

She explained, ‘It was just the lead up that made me freak out a little bit. But I’m happy to be 25.’

Kiernan previously explained that she’s been described as ‘wise beyond [her] years’ but started to feel ‘younger’ as she got older.

She told TheTalks: ‘People always told me that I was wise beyond my years. I never really believed them at the time but then I started to feel younger as I got older, if that makes any sense.’

The beauty elaborated: ‘I started to feel very professional at a young age, but then dealing with other life experiences was totally new to me. It was definitely unconventional.’

Earlier this month while chatting with People, Shipka dished on a holiday incident that led to her waking up with a facial injury.

She recalled the moment while promoting her upcoming Christmas movie Red One at its Berlin premiere.

‘I drank so much with my friends one night, and I woke up the next day and I had — I tell you — a mᴀssive hump on my nose,’ she recalled.

She described, ‘My nose literally went out a little and then back in.’

The actress said, ‘I don’t know if I fell,’ before adding that it was ‘unclear how it happened’ and that it ‘lasted a couple of weeks.’
