Jessica Biel reunited with her "7th Heaven" costars David Gallagher, Beverley Mitchell, Stephen Collins, Barry Watson and Catherine Hicks on Tuesday night, 18 years after the show's WB premiere.
Mitchell, who's expecting her second child, posted a family photo from the reunion on her WhoSay page this morning, writing, "Something truly amazing happened last night and my heart is overflowing!"
"Love these peeps more than I can ever explain! we were just missing Mack! Feeling so incredibly blessed to have these incredible people in my life!!! #theresnothinglikefamily #7thheaven #love #blessed," she added.
Mackenzie Rosman -- or "Mack" as Beverley called her -- was noticeably absent from the cute candid.
The actress has come a long way since she played little Ruthie Camden on the long-running series. The brunette beauty, now 24, recently made headlines for stripping down for Maxim, following in the half-naked footsteps of Alyssa Milano, Miley Cyrus, Danielle Fishel and Ashley Tisdale.
But, Rosman isn't the only Camden kid to take it off on a magazine cover!
There was some huge controversy when Biel decided to pose topless for Gear magazine. "7th Heaven" producers none-too-happy about the shoot, which was in huge contrast to the series' wholesome family vibe.
Jessica's character was eventually written out after the incident, though she did return for the series finale.
