Of course, we have heard these rumours before, but there are fresh reports that the actress and boyfriend Justin Theroux are expecting a baby.
Apparently, the 42-year-old was seen last week with a noticeable bump poking out of her coat.
A friend reportedly told Look magazine: 'She wouldn’t have wanted to make a big deal but she must be so excited. If anyone ever asked if she was worried about running out of time, she’d reply, "I’m absolutely having kids, there’s not one doubt in my mind."'
In October last year, Jen and Justin denied the rumours they were expecting after they were spotted leaving a clinic together.
The former Friends star's admission that she's quit smoking has done nothing to dispel the ongoing pregnancy rumours, either.
Jen and Justin have been dating since meeting on the set of Wanderlust in 2010 and have moved into a luxury apartment in New York together.
Lovely Jen has been rumoured to be pregnant on more occasions than we can count, but we would love it if this one were true!
