She added: “Grateful for how far I have come and excited for how much more I can continue to grow! I heard your thirties are the best.
“I thoroughly enjoyed the beautiful s**t storm, soul searching filled adventure I called my twenties... so I can’t wait to see what my thirties have in store.
“Let it be just as ridiculously joyous but also knowing more so when to let go of the stuff that no longer serves me,” she concluded.
Angie, who found love with boyfriend Carlin on the most recent season of The Bachelorette, then posted a cute video of herself and her beau to her Instagram Story.
In the video, Angie films herself standing in front of a mirror, while shirtless Carlin snuggles up close to the former Gogglebox star for a cuddle.
“Carlin was like... we should do a photoshoot,” Angie says through laughter.
"I didn't say that!" he responds, before whispering: "Don't tell them that".
She quips: "A couple's photoshoot!"
Angie’s heartfelt birthday reflection comes after she recently revealed that she and Carlin at times fight and struggle to make their relationship work in the real world.
Speaking to Outspoken the Podcast, the 29-year-old reality TV star admitted: "It's a real relationship so I'm not going to pretend that everything is okay all the time when it's not."
