A 2024 profile from Yahoo Entertainment identified her as his girlfriend, but the article noted that the two had not made any official announcement.

However, these sources are not reliable. In a 2024 interview with Anthem Magazine, Stark mentioned that his brother is a physicist and that their parents worked academic jobs. That contradicts the “only child” claim seen in some other profiles. The truth is that Stark does have a brother, but he is not a twin — the twin stories are fabricated.
