So the lucky Los Angeles Clippers star, who turned 29 last month, was understandably excited about one of his birthday presents, a signed photograph of his "first love."
"This is easily one of the best Bday gifts I've ever received in my 29yrs on this Earth!!!" Paul captioned an Instagram photo on Tuesday. "#KellyKapowski #My1stLove #WeWereTogether #SheJustDidntKnowIt #CuzImSavedByTheBell."
Thiessen, now starring on White Collar, retweeted the photo.
