Christina Kalamvokis

Starting out on social media around 2015, Christina Kalamvokis built her early following through lip sync videos on musical.ly, the platform that would eventually become TikTok, where she posted under the username stinakayy. Born on September 20, 1997, in Canada, she was roughly 18 when she first began creating content.

Rise Through Social Media

Christina's visibility grew considerably in 2017 when she began her relationship with Cyrus Dobre, one of the four Dobre Brothers, a family of content creators with a large combined audience on YouTube. By early 2018, she had expanded her social media presence more actively, and the couple launched their joint YouTube channel, Cyrus and Christina. The channel documented their day-to-day life and relationship milestones, and the pair cultivated a shared fanbase under the hashtag #Cyrina.

During this period, Christina also appeared in several videos on the Dobre Brothers channel alongside Lucas Dobre and Marcus Dobre, which helped expose her to a wider audience. She and Cyrus married in 2018, the same year their collaborative content output was at its peak. The couple announced their breakup in April 2020.

Career After the Split

Following the end of her marriage, Christina continued to maintain her individual social media accounts. She remained active on TikTok and Instagram under her established stinakayy handle, shifting her content away from the couples format that had defined much of her earlier output. She later launched a presence on OnlyFans, marking a move into a different content space from the family-friendly YouTube material she had previously been known for.

Profile

Christina is a Canadian creator who stands 5'0", placing her among the shorter models in the content space. She has brown hair, brown eyes, and an athletic build. Her measurements are reported as 32C-23-34. She has no visible tattoos or piercings.

With roughly a decade of activity across multiple platforms, from musical.ly to TikTok, YouTube, and OnlyFans, Christina's career reflects a path taken by a number of social media personalities who transitioned from mainstream content into adult-oriented platforms. She continues to operate her accounts as of 2026.
