The first trailer for Bridget Jones’s Baby has arrived and it’s got all the juicy details on how forty-something and single Bridget finds herself unexpectedly expecting.

It’s 12 years since we watched Bridget (Renee Zellweger) first fill her diary with diet updates and Daniel Cleaver; now she’s back with an iPad, maternity wear and a dashing new American suitor.

But it wouldn’t be life without a little complication – like who’s the father to her child?

From a dream wedding (literally) to an unacceptable dearth of Christmas jumpers, here are five things we’ve learned from the new trailer.

1. Bridget’s pregnant.

Ok, it’s kind of obvious from the title that Bridget has found herself with a bun in the oven and not just two tubs of Ben and Jerry’s, but the paternity is still a mystery.

There’s “at least a 50% chance” it could be ex Mark Darcy’s (we’re still in the dark as to how that heartbreaking split occurred) or new love interest Jack Qwant’s, played by Patrick Dempsey.

“A 50% chance? Did you have a three-way?” asks her horrified mother (Gemma Jones).

2. Patrick Dempsey is still McDreamy.

Only Bridget could fall face-first into a muddy puddle at a festival and find Prince Charming hauling her out.

The Cinderella-style shoe moment had us going all kinds of gooey over Patrick Dempsey and wondering what part of London we need to move to to meet Bridget’s fairytale suitors.

Suffice to say, that McDreamy nickname isn’t ready for retiring just yet.

3. “This is a unique and wonderful moment…”

A VIP-packed party gives us a glimpse of Ed Sheeran’s brief cameo, but it’s Emma Thompson who steals the show.

Playing Bridget’s obstetrician Dr Rawlings, she’s forced to do the confused mother-to-be a little favour and welcome both potential fathers into the room for the first ultrasound in a brilliant scene.

Emma is also credited as one of the writers of the film, alongside author Helen Fielding and Dan Mazer, so we can safely assume it’s going to be hilarious.

4. Bridget’s way out of her depth.

“Everything is completely under control… sort of,” Renee narrates, and it wouldn’t be Bridget without a few catastrophes on the road to happiness.

Perpetually-dieting Bridge hasn’t escaped the lure of the latest exercise craze, which looks like a nightmare spin class-disco combo with London’s lithest-limbed beauties on either side.

It’s not much better at work either where the hotshot TV producer is still having to cope with young upstarts who don’t take her seriously. At least she still has Shazza, Tom and Jude to share some large glasses of Chardonnay with.

5. Where are the Christmas jumpers?

We don’t want to panic you, but there’s a scene that looks very much like it’s set at Christmas (tinsel on the staircase and whatnot) and there’s absolutely no ugly Christmas jumpers in sight. In fact, when her dad pulls her in for a hug, she’s wearing boring old black.

But we do get to see Bridget in a wedding dress, plus her mum sporting a rather fetching “Vote Pamela Jones” rosette – are a wedding and a political career on the cards?

Bridget Jones Baby is out in cinemas on September 16.
