As she and Ryan Gosling enjoy their post-reunited bliss, Eva Mendes may be considering taking a huge next step in her relationship.

Gosling Calls Mendes His 'Muse?'

According to Radar Online, Mendes is trying to convince the 33-year-old actor that they should have a child together, and is enlisting the help of single mom friend January Jones to make her case.

"Eva is spending a lot of time with January and her two-year-old son Xander," a source said. "She's going overboard with her supportive relationship with January, who has her hands full as a young mother at the moment."

George Clooney Comes Between Ryan Gosling and Eva Mendes?

Mendes, who has previously not expressed an interest in children, may be trying to prove to Gosling that she has changed her tune and is now interested in being a mother. The two reportedly split over the holiday season last year because of issues including disagreements over having children. However, now that they've reportedly reconciled, she had changed her mind and now wants to have a baby with her on-again off-again boyfriend.

"Eva seems obsessed with proving to Ryan that she's ready to start a family," the source said.

Mendes, who reportedly passed on the idea of having children with previous boyfriend, Peruvian filmmaker George Augusto, has said in the past that being a mother wasn't on her list of priorities.

"I'm certainly not thinking about becoming a mom, " she said. "I can't imagine it. I'm too selfish."
