Christina Hendricks looks glum while out for a walk with the dog... only days after announcing her split from husband Geoffrey Arend

She shocked her fans and followers on Thursday by announcing that she and her fellow actor husband Geoffrey Arend were going their separate ways.

Christina Hendricks was spotted out on Monday after her separation announcement as she took one of the couple's dogs out for a walk on the set of her NBC crime–comedy Good Girls in Los Angeles.

The 44–year–old Mad Men star looked understandably glum and favored a relaxed, casual look. 

Christina was dressed comfortably in a gray baseball shirt with black sleeves.

She paired the minimalist top with a pair of high-waisted dark blue jeans. 

The 5ft7in beauty had on a set of short black boots and she carried along a black coat for a drop in the temperature.

Christina had a large black and beige bag slung over one arm, with thick straps decorated with partially obscured white text.

Though she's famous for her eye-catching red locks, Christina had dyed her hair a strawberry blonde shade for filming her series, now shooting its third season. 

This was the second sighting of Christina since she announced the end of her 10-year marriage on Thursday.

She was previously pictured looking downcast outside her LA home on Friday wearing a 'Welcome to the Badlands' T-shirt, black jeans and Birkenstocks. 

She had no make-up on and still had her signature fiery red hair, which was wet and scraped back off her face. Her wedding ring had been removed from her finger.

She greeted two removal men who had rolled up in a big moving truck outside her property.  

It comes just a day after the actress and her husband, 41, each shared an identical post confirming they had gone their separate ways. 

'Today we take our next step together, but on our separate paths,' they explained. 'We will always be grateful for the love we've shared and will always work together to raise our two beautiful dogs.'

They began the post: 'Twelve years ago we fell in love and became partners. We joined our two amazing families, had countless laughs, made wonderful friends and were blessed with incredible opportunities.' 

The former couple asked for space to 'rediscover ourselves' during the split.

'We will be taking time to rediscover ourselves in this transition and we thank you for your patience and support in giving us the space to do so.'

The two married in New York in 2009. They have no children together. 

Back in 2012 Christina recalled how she 'freaked out' Arend when she told the 500 Days Of Summer actor she wanted a family with him soon after they met in 2007.

Hendricks and Arend were introduced by her Mad Men co-star Vincent Kartheiser - and she said she found herself immediately drawn to him.

Christina told the UK edition of Cosmopolitan in the interview: 'Geoffrey walked in and I was like, "Who is this guy?" He had amazing hair and was all disheveled - he was running late and everyone was waiting for him. He just came in with this very high energy.

'He was just charming, funny and very magnetic. I got his number that night under the pretense of, "We could just be friends." And of course I immediately went home and Googled him.'

After a few weeks of the pair meeting as part of a group, they finally had a date, and then it was Hendricks who said the L word first.

She said: 'I cracked it out in such a big way. I was like, "You make me want to have a family." I freaked him out a bit...Thank God I didn’t spook him enough to make him leave.' 

In an interview in 2014, Toy Story 4 star Christina said the couple had decided against having children.

She told Health magazine: 'We've decided that we are not really interested in having children. It seems like it's expected that you'd want to have kids.It's just very normal for people to say, "Well, when you guys have kids..."

'And then when I say, "Actually I don't think we're going to do that," people will say, "Oh, you say that now..." It doesn't bother me, though.'
