Britney Spears reportedly sees her boyfriend as a "third son".
The 32-year-old singer has kids Sean and Jayden with ex-husband Kevin Federline. Following their divorce she got engaged to her manager Jason Trawick, who she split from in January last year.
Shortly after this Britney began dating her current beau David Lucado and the pair have been pictured out together regularly.
While their relationship appears to be going well, insiders claim the popstar is sceptical about whether David is the right man for her.
"Britney has been having doubts since before Christmas. She really fell for David at the start of the romance, but now she feels she jumped into things too quickly after splitting from Jason," a source told British magazine Closer.
"She was so desperate to have someone by her side. Britney's worried he's not mature enough for her - she's used to being spoiled by her boyfriends but, with David, she's been joking to friends that he's like a third son."
Britney began her two-year Las Vegas concert residency at the Planet Hollywood Resort & Casino last month. This is another reason why the blonde star is said to be questioning her love life and future.
"Britney's really torn because she still likes David, but she doesn't see their relationship ending up in marriage. She was so relieved he didn't propose at Christmas after hearing from friends he was keen to pop the question," the insider added.
"She starts her next stint of concerts in Vegas in February, so she doesn't want to rock the boat. But she's feeling the romance has lost its spark and she doesn't want to string him along if there's no future."
