However, one person not present to appreciate the mother-of-two's glamorous appearance was her 25-year-old boyfriend Smart.

Where's Casper? The pair exchanged gushing messages on Twitter for their anniversary

Jennifer's solo red carpet attendance came just two days after she kept herself occupied exchanging gushing messages with her man to celebrate their one-year anniversary.

The singer kicked off the messaging, telling her 'Bear' Casper: '@BEAUcasperSMART BEAR!!!!!!!!!!!!!! Today is OUR's!!

'Thank you for sharing your beautiful smile with me everyday! ?#SpecialDay #LOVE! (sic)'

Casper! then rep! lied: '"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, 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 but I still believe in love. That would be my message: love is the most important thing.'

Perfect from every angle: Jennifer looked sultry in her outfit, while Eva Herzigova also opted for a black dress
