The couple - who refer to each other as "bear" - sent sickly sweet messages on the micro-blogging site on Thursday (25.10.12) to mark a full year since they first began dating.

Jennifer wrote: "?@BEAUcasperSMART BEAR!!!!!!!!!!!!!! Today is OUR`s!! Thank you for sharing your beautiful smile with me everyday!

?#SpecialDay ? ?#LOVE! (sic)"

Casper, 25, replied: "Happy 1 yr. anniversary to the most Gorgeous, Kind, Sweet, Funny, Beautiful Lil Bear in the world.... Love Bear ?#October25 (sic)"

Despite three failed marriages, Jennifer, 43, who has four-year-old twins Max and Emme with her former husband Marc Anthony, recently insisted she still believes love is the most important thing.

She said: "You have to believe there`s somebody out there who is trustworthy, who`ll stick in there.

"It`s difficult when a family breaks up. I`m still living through it, just trying to do my best with the kids and moving on. It was one of the most difficult decisions I`ve ever made. It`s been tough "I still believe in love. That would be my message: love is the most important thing."
