The professional dancer, 41, took part in an impromptu Instagram Q&A on Wednesday which saw her answer questions submitted by her followers.
When asked: "How are you doing?" Karen responded with: "I'm OK I think," followed by a laughing face emoji.
In the revealing update, Karen filmed herself during what appeared to be a train journey. Embracing the changing weather, she donned an autumnal jumper in an eye-catching caramel shade.
She looked radiant in her cosy garment which also featured three military style buttons running down the neck. As for hair and makeup, Karen appeared fresh-faced and wore her raven tresses flipped over to one side for a fuss-free look.
Karen's new update comes amid swirling reports of her alleged split from her husband of one year, Jordan Wyn-Jones. According to The Mirror, the pair have gone their separate ways, but remain on good terms.
Whilst neither Karen nor Jordan have publicly spoken about their relationship, Karen surprised fans last week when she was spotted without her wedding ring at the Pride of Britain Awards in London.
HELLO! has reached out for comment.
This isn't the first time Karen has shared a sneak peek inside her private life. Back in August, the Venezuelan-born dancer spoke about dealing with "tricky moments" in her marriage during an exclusive interview with HELLO! magazine.
Opening up, she said: "So whenever we're having tricky moments or anything like that, it's just seeing the vulnerable side of each other and understanding it and knowing that both of us are working on things because nobody is perfect."
The pro dancer went on to say: "There is no such thing as a happy marriage or a happy relationship with the perfect couple. It's about dealing with things the right way and not just running away from things, and I guess that's what makes us tick even better and understand one another."
It's been a whirlwind couple of weeks for the dancer. On Sunday, Karen and her celebrity dance partner, Eddie Kadi, became the fourth couple to leave Strictly Come Dancing 2023.
The dancing duo faced Zara McDermott and her partner Graziano di Prima in the dance-off, but sadly failed to win over the judges with their lively Samba performed to Calm Down by Rema and Selena Gomez.
Following their exit from the hit dancing show, Karen paid tribute to her dance partner with a touching post.
On Instagram, she shared a carousel of behind-the-scenes photos of the couple, which she captioned: "To my best friend… @comeddiekadi. No one really gets to see the real Eddie behind the scenes.
"The man that works hard day in day out. Even on those rainy days that you didn't feel like smiling or telling a joke, you still pulled through and stayed true to yourself. Thank you for your friendship and your unconditional attention and support."
