And it involves Glee!!!
Watch (above) to get the scoop and then help us share the exciting news!!!!
Sienna Miller and her fiancé, Tom Sturridge, welcomed their first child together in London this past weekend!
Unfortunately, we don't have any details on the gender, name, or weight, but the actress made it perfectly clear throughout her pregnancy that she was planning on keeping her child out of the limelight, so we're not particularly surprised!
Just delighted for the new parents!
All the best, you two!
Congrats, congrats, congrats!
