How old are the children on "Jersey Shore"?

Why: I am watching the heartbreaking Season 2 finale finally (jk, this is like the 3rd episode I've ever seen). All these kids are jerks.

Answer: Way too old:

• Angelina - 22 (b. 1988)
  
• Jenni / JWOWW - 24 (b. 2/86)
  
• Mike / The Situation - 28 (b. 6/29/82)
  
• Nicole / Snooki - 22 (b. 11/23/87)
  
• Pauly D - 30 (b. 7/5/80)
  
• Ronnie - 23 (b. 5/13/87?)
• Sammi / Sweetheart - 23 (b. 3/14/87)
  
• Vinny - 22 (b. 11/11/87?)
  

Also, a new personal person will join the cast in Season 3 (which just finished filming back in the Dirty Jerz). Snooki's intelligent and orange friend Deena is 23.
