Though it's unclear when Wesley and Kuckenburg started officially dating, they were first spotted together in November 2022 as they enjoyed a romantic dinner date in Nerano, Italy.

After they were photographed sharing a kiss, they each posted photos from the same location on their Instagram accounts shortly after.
