Gavin Rossdale and Mindy Mann were reportedly engaged in a three-year affair prior to his divorce from Gwen Stefani, but what is their relationship like now?

Following news of Mann's pregnancy, fans are wondering if she and Rossdale have kept in touch -- and whether or not he could be the father of her unborn baby.

In a recent report by OK! Magazine, via Gossip Cop, the outlet confirmed Mann was pregnant, and claimed there’s “shocking rumors that the baby is Gavin’s.”

While Mann reportedly tagged her boyfriend, who is not Rossdale, in her Instagram announcement, the magazine's insider claimed Rossdale and Mann have “stayed close this whole time despite everything,” and described Stefani as being “rocked” by the possibility of Rossdale welcoming a child with the woman who was believed to have come in between them.

“It would crush her if her sons were related to Mindy through a half sibling,” the source alleged.

Luckily, it has since been confirmed to Gossip Cop that Rossdale is definitely not the father of Mann's child. However, he kept in touch with his former employee for at least several weeks after news of their affair hit the web. After parting ways with Stefani in Aug. 2015, Rossdale's vehicle was seen at Mann's day care center in Dec. 2015, and he was rumored to have had lunch with her just weeks ago.

As for what Stefani thought of Mann's baby news, an insider claimed she was far from concerned.

“[Gwen Stefani] is not worried about her former nanny right now. She is busy doing other things,” a source close to mother-of-three told Hollywood Life weeks ago.

“[Gwen Stefani] is a mother herself and deals with her day to day happenings with her kids. She is in a new relationship and getting over her past relationship [and] focusing on career goals,” the report continued. “The last thing on her mind is Mindy. She obviously doesn’t want anything bad to happen to her. She doesn’t harp on every move Mindy is making.”
