Singer Adele, 32, looked gorgeous as she shared a hilarious clip of her friend Nicole, 39, pranking her as she waited to scare her, in a post shared with her 39 million followers.
Nicole was seen hiding behind the entrance of a kitchen in the video before jumping out on her friend, leaving their fans in hysterics.
In another spot, Adele shared a snap of herself looking gorgeous in a fluffy white hat and laughing while Nicole looked out of a window behind her.
The third picture showed the pair posing with a giraffe as Nicole smiles at the camera while Adele appeared to be terrified by the large animal.
The fourth picture stole the show as Adele flaunted her incredible weight loss in an off the shoulder black velvet top on.
The singer reportedly lost a whopping 7st with the help of a lifestyle overhaul and a new personal trainer who gave her an intense exercise regime.
Tying her blonde hair back into a bun, Adele's weight loss commanded attention in the sweet birthday snaps, as she showed off her transformation.
The final picture showed Adele sticking her tongue out while holding a wine glass with a group of people with Nicole included.
She captioned the snaps: "Happy belated birthday to my daily dose of grace @nicolerichie I admire you and love you so much.
"You are the epitome of self preservation, self love and absolute savagery!
"You are so so cherished by so many angel girl! Keep making us laugh babes, we adore you to the moon and back," adding a red heart emoji.
Adele's latest social media display comes after she reunited with her rumoured love interest Septa, with pictures being taken of the pair together in London.
The pair reportedly went on a string of dates together last year, but hadn't been spotted together until now.
Adele and Septa, real name Joseph Junior Adenuga, were seen meeting in a London bar as a source told The Sun Online: "We were asked to move from the lounge because a VIP was arriving. I couldn’t believe it when Adele just walked in with Skepta and Jammer.
"After doing the VR I saw her chatting to people and putting her boots back on. She seemed really down to earth.
"They were screaming and laughing when they were doing the VR together, I could hear her from the other end of the venue. It looked like they had a lot of fun together."
