Bruno Mars’ Longtime Girlfriend Jessica Caban Wants More Than Just Friendship

Bruno Mars‘ music is a staple at weddings, but the 15-time Grammy Award winner is hitting a sour note with his gorgeous girlfriend, Jessica Caban, who has waited 14 long years to bop to the beat of a marriage proposal!

Mars, 39, began dating 42-year-old actress/model and Jane the Virgin alum Caban – but while the pair shares a lavish Hollywood mansion, a friend says that in recent years they have become little more than roommates.

“Jessica has stuck by Bruno all these years, even without a promise of marriage, much less starting a family,” spits a source.

“But she feels he takes her for granted. They didn’t even spend the Christmas holidays together! She’s at the point where she can’t stand for things to continue this way.”

But Bruno-who says he wrote his hit When I Was Your Man for Caban, has consistently danced around the idea of getting hitched, saying, “She’s my best friend.

What’s wrong with that?” But the pal persists in claiming that Caban bristles at her “best friend” status and has told Mars he needs to step up his romance game or else! ”

Jessica says she has plenty of friends. She wants an attentive lover, but she’s been feeling like she’s just window dressing in Bruno’s life,” blurts the buddy.

“She’s let him know she’s ready to bolt if she doesn’t get showered with love and affection but the sad thing is, Bruno seems oblivious to her wishes, and it’s going to doom them!”
