Why J-Rod Could Get Engaged Over the Holidays: 'There Are Definitely Talks About Marriage'

Could Jennifer Lopez be getting a very big (and shiny!) present from Alex Rodriguez for Christmas?

According to a Lopez source, the superstar couple are looking forward to a future together with their kids and could very well get engaged over the holidays.

“All the kids want Jennifer and Alex to get married,” the source tells PEOPLE exclusively. “There are definitely talks about getting married, but Jennifer is old-school and will wait for the engagement ring before she entertains any wedding talk.”

For all the details on J-Rod’s relationship and their plans for the future, pick up the latest issue of PEOPLE, on newsstands Friday.

Rodriguez, 42, is a doting dad to Natasha, 13, and Ella, 9 (with ex Cynthia Curtis), and Lopez, 48, is a hands-on mom to her 9-year-old twins Max and Emme (with ex Marc Anthony).

“They are very happy that all the kids get along and have accepted their new family,” adds the source. “Jennifer feels Alex is her true soulmate and can’t believe how happy she is with him.”

Rodriguez — who “smiles any time marriage comes up,” says the source — is also head over heels for the actress, who’s been hard at work on her upcoming film Second Act in New York City.

The pair plan to celebrate the holidays in Miami and also get some much-needed rest and relaxation in the Bahamas, adds the source.

“I get to do a lot of fun things with Jennifer,” the retired baseball star and entrepreneur told PEOPLE earlier this year. “I’ve learned a great, great deal from one of the most amazing women I’ve ever met.”
