The superstar baby boom continues, with news that British actress Sienna Miller is pregnant to her boyfriend Tom Sturridge, Us Weekly reports.

The former Jude Law flame spent the last week of 2011 in Paris with her boyfriend, reportedly as a celebration of the baby after telling friends in London.

Sienna split with Jude for the second time in February and is reportedly fed up with his drama and cheating. Jude famously cheated on Sienna with his children's nanny in 2006. Tom and Sienna have been dating for a year.

While Sienna's rep couldn't be reached for comment, Sturridge's commented that they "don't comment on our client's personal lives at all."

30 year old Sienna and Tom, 26, don't have any plans to marry at this stage, if at all.

Do you think these two will last the distance?
