In the photo, Lucy can be seen looking coyly up at the camera, a small smile on her lips, while co-star Tom kisses her cheek.
Lucy revealed in the caption that they were cuddled up together to watch Sunday's episode of the reality show.
In the latest installment, viewers saw the couple's relationship blossom further as they enjoyed a romantic dinner out together. Being TOWIE, the date wasn't without its dramas. The couple dined at the same restaurant as Lucy's ex Mario Falcone and his new lady Lauren Pope.
After admitting she was still in love with former fiancé Mario during Wednesday's episode, Lucy has said she is ready to move on. She took to Twitter to tell fans, "Mario is my past and I just want to move on now. I think it's best for both of us."
Speaking about her romance with Tom, she added, "We are officially seeing each other, but we're not officially boyfriend and girlfriend yet."
Fans saw Lucy and Tom get together during the show's stint in Las Vegas – but it appears that sparks first flew in Ibiza.
Lucy recently posted a cosy picture of the pair cuddled up with the caption, "Where it all began #Ibiza2013."
Now back on home turf, the couple look set to continue their romance. The fashion boutique owner has also shared a photo of a beautiful bouquet of flowers sent to her by her new man.
