She’s had her fair share of sour romances, and Lady Gaga is reportedly a bit worried that her recently rekindled relationship is in trouble.

The “Alejandro” singer recently got back together with Luc Carl, but now is said to have found out that Carl is still seeing his ex flame.

A source tells Britain’s Grazia magazine, “She’s only just got back together with Luc and now she’s frightened she’s going to lose him again because she simply can’t trust him. She’s also upset because this seems to make her the ‘other woman’.”

Gaga previously dated Carl five years back – before she was famous – but the two parted ways as the “Poker Face” singer tried to curb her drug usage.

“GaGa has built this whole career and she had to prove she could do it,” the insider tells. “But in her personal life she feels like a fool because she still can’t make the man she loves love her and only her. Luc’s ex told her they were still together. She was so upset. Luc had promised GaGa he’s treat her like a princess and all the hurt was in the past. GaGa says it’s a matter of self-respect now and she may have to end it because she’s just not high enough on his list of priorities.”
