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.''
