'Bridget Jones' Baby' trailer: Renee Zellweger is having a baby and a run-in with Ed Sheeran

After a 12-year hiatus, Bridget Jones is back.

And still single.

"Not to dwell on the negatives -- many positives to note -- I'm absolutely loving my new life," says Renee Zellweger in the first trailer, just after her signature tune "All By Myself" plays. She is then seen taking on spin classes, work woes and a run-in with Ed Sheeran -- and, oh yeah, a surprise pregnancy.

But who is the father? Thankfully, Emma Thompson helps out by conducting two ultrasound reveals for both returning actor Colin Firth and new addition Patrick Dempsey.

Sharon Maguire, who helmed the original Bridget Jones's Diary, directs the third film based on creator Helen Fielding's heroine.

Zellweger stopped by Wednesday's episode of The Ellen Degeneres Show to premiere the trailer.

Universal will release Bridget Jones' Baby on Sept. 16.
