Earlier this month Christina Hendricks said she doesn't use social media because her feelings would get hurt by trolls online.

But in the world of Hollywood, things change quickly.

The Good Girls star, 44, has finally joined the world of Instagram with her first post on Thursday, and she's getting a warm welcome from her friends, namely, 41-year-old actress January Jones.

One of us! Christina Hendricks finally joined the world of Instagram with her first post on Thursday

Fans and friends: Her Mad Men pals January Jones and Kiernan Shipka were quick to welcome her to the platform

'Hello world. I'm here with a little help from my friends,' Hendricks wrote in the caption of her first Insta post on Thursday. 'Let's do this.'

The Mad Men actress posted a selfie in retro round sunglasses while her warm red hair falls over her shoulders in voluminous curls.

And gal pal January Jones jumped right in to congratulate her, commenting on the Tin Star actresses' picture, 'So exciting. Peer pressure is an amazing thing.'

19-year-old Kiernan Shipka also took to the social media site to welcome her Mad Men co-star, posting a comment that read, 'heyyyy girl.'

Peer pressure: 'It’s actually happened, I thought I’d never see the day! Let’s all welcome @actuallychristinahendricks to Instagram,' Jones wrote (pictured with Mad Men co-star Jon Hamm March 2015 in New York)

And Jones took it one step further, re-posting the photo on her own Instagram page.

'It’s actually happened, I thought I’d never see the day! Let’s all welcome @actuallychristinahendricks to Instagram,' she wrote.

The Good Girls actress already has 24,000 followers...and the list is growing by the second.

But just two weeks ago, during a visit to her talk show Busy Tonight, the Mad Men vet told Busy Philipps, 39, that she doesn't use social media.

'I have a reaction to it,' the Good Girls star said. 'I think I'm very sensitive and I think I might get my feelings hurt.'

Outside of avoiding mean tweets, Hendricks also revealed she is worried she would become far too infatuated with the people she follows.

'I think I might get obsessed and just go through people's lives all day long,' she confessed.

Philipps jokingly admitted that she has a problem with it, too.

But, in an effort to change the leading lady's mind, Philipps then read a series of nice things fans had said about her on social media.

One fan wrote, 'I think Christina Hendricks might be the most beautiful person alive. I'm going to need to see her in person next to Idris Elba to be sure.'

And another wrote, 'Christina Hendricks in @nbcgoodgirls is so good and we are not talking about this enough.'

Perhaps those nice messages were all Hendricks needed to change her mind.
