New photos on Lorraine's Instagram show the pair relaxing in white bathrobes as they enjoy a chilled Sunday together.
In one, Lorraine and Clair, who plays her on-screen daughter Bernadette, smile for the camera and Lorraine wrote for her followers in the caption: "Feeling fresh @champneysspas #nofilter #nomakeup @clair_norris #natural #spa #relaxation #girlietime."
In another post, the pair laugh as they lounge in a set of huge egg chairs and don their swimming costumes for a dip in a pool.
Lorraine captioned it: "Two peas in a pod..."
On her own Instagram, Clair posted about the trip and revealed it was a "lovely treat" from her on-screen mum.
She shared a string of photos of the grounds at Champneys, a health spare centre in Hertfordshire.
"@champneysspas we have arrived!" Clair said in the caption, adding: "First treatment done, thank you @lorraine_stanley_ for this lovely treat."
Lorraine's no stranger to hanging out with her co-stars outside of filming hours.
Earlier this summer, the star enjoyed a trip to Majorca with what appeared to be half the EastEnders cast.
Two peas in a pod...
Showing they clearly don't see enough of each other at work, Lorraine posted a picture of herself with other cast members on the Spanish isle.
Max Bowden (Ben Mitchell) also posted a pic of himself with co-stars Danny Walters (Keanu Taylor), Jamie Borthwick (Jay Mitchell) and Steve McFadden (Phil Mitchell).
Lorraine's picture showed her sitting with Jamie, Danny and Max, as well as her partner, Mark.
Fans loved the snap, with one writing: "Now that's a table I wouldn't mind sitting at!"
"How amazing, imagine the banter," said another.
A third added: "Squad goals!"
Others wished them a lovely holiday and said they can't wait to see their tans on screen, while another fan commented on Danny's hair as it appeared much longer in his holiday snaps.
