Her relationship with ex-husband Ryan Sweeting was one which she constantly documented on her Instagram account, but Kaley Cuoco seems to be taking a wildly different approach with her romance with Arrow star Paul Blackthorne.

Kaley Cuoco Going Up Against Josh Gad On 'Lip Sync Battle'

Cuoco has been rumored to be dating the actor since late last year, but there's been no photos or mention of him on her social media accounts--and the two haven't been spotted out in public together either, with Cuoco attending events with family, friends or alone.

Comparatively, after going public with Sweeting just before their engagement, Cuoco attended most events with her husband by her side, and often documented their relationship on her Instagram account. Even as rumors circulated that their marriage was in trouble, she posted defensive photos of him, saying that their relationship was fine.

However, those posts were all deleted--as was virtually any trace of Sweeting--from her account, after they announced their divorce.

Since then, her rumored romance with Blackthorne has been very low-key. The only mention of him on Cuoco's Instagram had to do with a charity he supported to help end poaching two months ago.

However, despite the lack of documenting the relationship on social media, sources close to Cuoco have said that her new romance is going well, and that she's been happy since her split from Sweeting.

Her sister, Brianna, has even gone on the record to say that her sister is the best she's ever been.
