Look: 'Hart to Hart's Robert Wagner, Stefanie Powers reunite on his birthday

Feb. 13 (UPI) -- Former Hart to Hart co-stars Robert Wagner and Stefanie Powers reunited over the weekend.

Powers, 81, was among the family and friends at Wagner's 94th birthday dinner Saturday.

Powers shared a photo Monday on Instagram from her reunion with Wagner. The picture shows the pair smiling for the camera as Powers rests her hand on Wagner's shoulder.

"Happy Birthday (2/10) to our dear Robert Wagner. 94 and still going strong! Our latest Hart to Hart moment," Powers captioned the post.

Wagner and Powers played Jonathan and Jennifer Hart, a wealthy couple who often found themselves working as amateur detectives, on Hart to Hart, which had a five-season run on ABC from 1979 to 1984.

The pair later reprised their roles in a series of Hart to Hart movies, the most recent of which, Till Death Do Us Hart, was released in 1996.

Wagner shared a video Monday that showed him giving a toast at his birthday dinner.

"Thank you for making my birthday so special. I love you all so very much," he said in the caption.

Wagner's more recent roles include Teddy Leopold on Two and a Half Men and Anthony DiNozzo Sr. on NCIS.
