The 30-year-old shared the adorable snap with her fans on the social media site, writing:
“Cheers!!!!!!!! To the most memorable night of my life thus far @devinlucien”.
Showing off her new stunning ring, Kaitlin sported a giddy smile on her face as she also posed with a glass of red wine in her hand, and a cute navy blue and maroon manicure on her nails.
The ring has a wide-set band with detailing and an oval diamond set in the middle.
The large ring appears to match Kaitlin’s quirky style, as in one of her pictures the ring can be seen sat alongside other intricately-designed rings.
Kaitlin’s fiancé is DJ Devin Lucien, and the musician proposed in what many believe to be the most romantic city in the world – Paris.
“SHE SAID YES!!!!! @kaitlindday,” wrote Devin on his own Instagram account, sharing a picture of Kaitlin with a huge grin on her face.
A second picture posted on Wednesday saw Kaitlin showing off her ring again with the caption: “Paris is so beautiful isn’t it????”
Kaitlin’s picture continue to cause a frenzy amongst celebrities such as Christina Aguilera and Lauren Conrad who not only sharing their happiness and excitement with fans, but also post what is now referred to as the “hand selfie”.
