Sarah Jessica Parker recently praised her "Sex and the City" co-star, Chris Noth, in the comments section of a workout snap.

“Climbing the mountain of time and gravity!” Noth wrote on Instagram July 13, when he posted a photo of himself on a weight bench.

Since it was posted, the 63-year-old actor’s image has received more than 12,000 likes and 400 comments.

Parker weighed in in the comments section, writing, “Still looking good!!!! X.”

Further down, Noth tagged the 53-year-old star’s Instagram handle.

The actors’ characters had an on-again, off-again relationship on the comedy series before reuniting in the series finale.

“And still looking good!!” one user said.

“You are like fine wine,” a commenter claimed. “You get better and better with time.”
