Paulin previously attended a service with Bieber on September 27. "They met earlier in the day and he insisted she go to church with him," a source told Us at the time, adding that the pair later "had an intimate, private date."

Reunited!

Kardashian, 38, headed to church separately with a female friend. The Keeping Up With the Kardashians star rocked a white sweater, skinny jeans and white pointed-toe heels. As Us Weekly exclusively revealed in December 2015, Kardashian and Bieber began hooking up after her split from longtime love Scott Disick that summer. "Every time Kourtney and Justin are together they're extremely flirtatious," a source told Us at the time. She is now dating model Younes Bendjima.

Last but not least, Baldwin, 20, arrived at Wednesday's service in a black and tan bomber jacket, black leather pants and white high-top sneakers. The model, who is the daughter of actor Stephen Baldwin, was linked to Bieber in early 2016, though their dalliance was short-lived.
