Josh Duhamel is “head over heels” for new girlfriend Eiza Gonzalez, but the actor is keeping the romance hush-hush out of respect for his ex-wife, Fergie, a source tells ET.
"Josh is head over heels for Eiza, but he felt guilty that he had feelings for another woman so quickly and he wants to be respectful to Fergie so he has kept this relationship very, very private," the insider says.
“Josh is a very good man and wants to be respectful to the mother of his son,” the source adds. “He wants to make sure Fergie knows he supports her life and her future. He is being so loving and respectful to Fergie and making sure she knows he is there for her.”
As for why the pair couldn’t overcome their differences and mend their marriage, the insider blames the different lifestyles the two wanted.
“Fergie loves her career and the fast-paced life of Hollywood and being in the public eye,” the source says. “Josh is a little more low-key and wanted more of a home and family life.”
“Despite growing apart in their marriage, they have remained very close as friends,” the insider adds. “Fergie knew that Josh was ready to move on … toward the end of their marriage, they were leading such busy and separate lives that very few of their friends even realized they were no longer in love.”
“We have full-on practices at the house," the Love, Simon star shared. “I'm putting little pieces of candy at each base. If he hits it past me, he runs to first base. He has no idea [he's training], he just wants the candy. But he's learning how to hit -- I'm making him hit from both sides of the plate."
"This is why I wanted to be a dad,” Duhamel continued, "to be able to have moments like this with him."
ET has reached out to Duhamel and Gonzalez’s reps for comment.
