Tom Pelphrey's 40th year is starting with a (big) bang in the form of a sweet birthday tribute from Kaley Cuoco. "To the incredible man that saved me in all the ways. Happy birthday, baby!" the actress wrote on Instagram alongside a snapshot of the actor smiling. "To know you, is to truly adore you … the world lit up the day you were born. I love you!! @tommypelphrey." Cuoco and Pelphrey made their romance Instagram official in May and attended their first red carpet event together later that month. The Big Bang Theory alum was previously in a relationship with equestrian Karl Cook. However, they announced their breakup in 2021 after three years of marriage, noting that while they have a "deep love and respect for one another," they realised their paths were taking them in opposite directions. It looks like she's found that love with Pelphrey. In fact, the Outer Range star has let his feelings for Cuoco be known, calling her his ‘favourite person’ in one Instagram post and celebrating her second Emmy nomination in a row for her role in The Flight Attendant.
