According to multiple sources, the World of Dance judge and former professional baseball player have been house hunting together, Peoplereported.
Jennifer, 48, recently listed her home in New York City, asking for $27 million.
The actress and Alex, 42, are now "looking for an apartment together for the whole family," a source close to Jennifer told the magazine.
Jennifer And Alex began dating in February 2017, and ever since then, have been bonding with each other's children and families. Jennifer is mom to nine-year-old twins Max and Emme, while Alex has two daughters -- Natasha, 12, and Ella, 9.
"They will invest together in a new home when they find the perfect one," the source told People. "They are starting to make more financial decisions together. It's nice for Jennifer to be with a man who has his own money and spends it wisely."
The couple also shares a desire to help others in need, as they've jointly raised and donated tens of millions of dollars for hurricane victims over the last few weeks.
"They are equally passionate about different causes and charities," the source explained. "Jennifer has been upset about the Puerto Rico situation. She knew she had to help. Alex has been very supportive and encouraging."
"Jennifer is truly the happiest she has ever been," the source told People. "They really just complement each other and make each other better people. She thinks the world of Alex and is very excited about their future together."
A friend of the lovebirds added, "They are similar in that they are the embodiment of working towards your dreams."
