Beyoncé Knowles apparently "completely trusts" Jay Z because he is such a devoted family man.
The rapper married Beyoncé Knowles in 2008 and they have daughter Blue Ivy together.
Their strong union was rocked last week after little-known rapper LIV came forward with cheating claims.
LIV revealed Jay had tried to seduce her on the set of a commercial just months before he tied the knot with Beyoncé.
Sources say the couple have not been fazed by the allegations, as the way Jay has taken to fatherhood and his family is proof of his commitment.
"Jay is the most amazing, doting father and Beyoncé trusts him completely," a source told British magazine Look. "She would never question him over something as trivial as this kind of nasty gossip - Bey is way stronger than that and this rapper could never come between them because he lives for Blue Ivy and Beyoncé - she's beyond sure he'd never jeopardise what he has with them. "
The insider added that the couple have made a pact not to let jealous individuals destroy their close bond.
Both the stars are aware that people will do almost anything to get a slice of their fame, and Beyoncé is thought not to have even raised the subject with her husband as it's so ridiculous.
"They've made it through worse rumours so there's not a chance this will damage their marriage," the source finished. "They're both just ignoring the whole thing, it's barely been a blip on the radar."
