The cute couple just made things Instagram official during a trip to Ireland.
In the series of snaps, Kate and Justin can be seen taking a shared sip of a pint of beer – then rocking mustaches in beer foam.
In the comments, Kate chimed in to add, “I’m the luckiest. 🍀✨😘”
Since then, the low-key couple have been spotted several times, including on a recent PDA-filled trip to Hawaii.
While the couple kept things private early in their relationship, Justin recently opened up about Kate for the first time.
“There’s something about it, for me, that I feel like I have to protect and keep sacred because it feels sacred to me,” Justin in an episode of the Dear Chelsea podcast.
He added that being “in love” is “such a wonderful feeling” and that he had “never had anything like this before”.
Justin has previously been linked to Drew Barrymore and Amanda Seyfried while Kate split from ex-husband Michael Polish last year.
It’s so nice to see that Kate and Justin have found love with each other!
