We know that actors work hard in order to look good ... but the ones on this list take it to extremes as they never seem to age. EVER.
Have they found the fountain of youth, a great plastic surgeon or are there vampires roaming our TV screens? You decide...
1. Ben McKenzie - Then and Now - Gotham
Back in 2003 he was Ryan on The O.C. Now he's the formidable Detective Gordon on Gotham. Plus there was a stop in Southland along the way, but other than the hair, not much has changed.
2. Jennifer Love Hewitt - Then and Now
She was a teen idol of the 1990s but she's only gotten more beautiful as the years have passed. From 1998 to 2013 when she was starring in The Client List, not much as changed. Now you can check her out on the CBS hit crime drama, Criminal Minds.
3. Pauley Perrette - Then and Now
From NCIS season 1 to season 12 Pauley Perrette still looks as young as when she began. When we read that the actress was supposedly 46 years old we had to wonder, has she found the fountain of youth or could she be a vampire?
4. Gabriel Mann - Then and Now
Does anyone actually believe that this man is about to have his 43rd birthday? I didn't think so. From 2001 to the present, Gabriel Mann appears to have stopped the effects of aging. Really high-end moisturizer or vampire?
5. Ming-Na Wen - Then and Now - Agents of S.H.I.E.L.D.
We first remember Ming-Na on NBC's hit medical drama ER in 1995. Now we see her kick butt every week on Marvel's Agents of S.H.I.E.L.D. You decide if she's aged.
6. Jennifer Aniston - Then and Now
Seriously, this woman only gets more beautiful with age. When we were all watching Friends in the mid-90s, little did we know she'd be this stunning 20 years later.
