Britney Spears has reportedly been warned to "slow things down" with her new boyfriend.
Spears married Kevin Federline in 2004 and together they have sons Sean and Jayden James.
The couple divorced in 2007 and since then Spears has been engaged to Jason Trawick, who she split from at the beginning of this year.
The pop star is now dating legal firm researcher Dave Lucado and Federline is reportedly concerned about their fast-moving relationship.
"Kevin doesn't want the kids to think that any man that Britney dates will ever replace him as a father figure," a source explained to British magazine Star.
"This is the second man she has had staying at her house and he fears it could upset the children... Ultimately he has Brit and their kids' best interests at heart but he thinks she is diving in too soon with Dave and she needs to slow down."
Spears and her new beau were first spotted together in February, when they enjoyed a Valentine's Day date together.
The troubled singer seems to be in a good place and has even settled her differences with Kevin in order to co-parent their boys.
It is thought that Federline may have raised the issue of Britney's new relationship while spending time with their kids together.
"They have had more time to chat at their boys' soccer games recently and Kevin told her he isn't happy about her bringing in another man to their lives so soon after Jason," the insider continued.
"Kevin is conscious of the impact it will have on their lives and wants their upbringing to be as stable as possible."
