"It is already Sept 22nd right now in Australia so HAPPY BIRTHDAY G!!!!" Stause captioned a slideshow of photos of herself and G Flip. "Imagine you took all of the things you love about an emotionally intelligent secure man, and all the things you love about a strong loving caring woman, and blended them together to make one magical human. Oh and it would be cool if they could also be a sexy musical genius that is hilarious and maybe give them a hot Australian accent too because why not.🤯"
Stause went on to share her favorite thing about the non-binary musician, adding, "Even though I could list a million things I love about you, your kind genuine heart is my absolute favorite. I feel extremely lucky to be able to celebrate you constantly but especially today."
G Flip took to the comments section, writing, "BABYYYY!!! Thank you! This is so cute arhhhhh," adding several wide-eyed emojis, and continuing, "I adore and love every inch of you darling ❤️"
The couple first went public with their romance in May after Stause starred in G Flip's steamy music video for their song, "Get Me Outta Here."
ET's Cassie DiLaura spoke with G Flip about filming the video with Stause.
"As long as she was comfortable, then I was stoked," G Flip shared. "She's got acting chops because of her soaps and stuff, [but] me, I don't. So it was really nice having a co-star that when the cameras are go, it's just ready to go. She's a superstar... She's so awesome."
Stause spoke with ET's Denny Directo in June at the MTV Movie & TV Awards about the possibility of sharing her love story on Selling Sunset.
"I gotta be honest. I don't know. It seems a little scary," she told ET at the time. "That's a bridge we gotta cross."
