Coming to contradict all those who said they wouldn’t last, Jennifer Aniston and Justin Theroux are talking about getting married soon. Not only that, but they’ve also decided to start trying for a baby immediately, says a new report.

The two actors are now in Hawaii on an extended holiday – and sources close to them are telling the latest issue of Us Weekly that they want to start trying for a baby while still there.

In other words, things are getting serious between them, and they are one hundred percent convinced that they’re with the person they’re going to be spending the rest of their life with.

“They have talked at length about getting married and starting a family. She is anxious for the next phase of her life and feels like this is the time,” says the spy, who refuses to go on the record with a name but professes to be close to the two stars.

Aniston is not the only one dreaming of a family in the immediate future either, since Justin too is pretty excited about the idea as well.

“They both want it to happen soon,” the insider dishes.

Because she’s determined to do her best to make sure the child is healthy, Jennifer is already preparing for the pregnancy.

“To that end, health nut Aniston is making sure her body is in tip-top shape to conceive while on the island – hiring a private chef and doing at least 45 minutes of yoga daily. ‘She’s detoxifying,’ an island source says,” Us writes.

If fans are shocked that things are happening so fast and may think that Jennifer is rushing into the relationship, they shouldn’t fret: the magazine reports that her friends are not in the least bit surprised that she’s already talking about marriage and kids.

“Jen hasn’t felt this way about anyone since Brad,” says another source.

“They are moving quickly, but they know the feelings they have about [each other] are different from past romances,” the pal adds.
