Girls all over the globe are weeping this morning...

The Transformers: Age of Extinction star is set to tie the knot with Madeline Mulqueen after he popped the question recently following two years of swinging out of each other, according to People magazine.

Rumours of a possible engagement began circulating late on Tuesday when the Irish model was spotted wearing a large sparkler on her ring finger as she worked on a pilot for the TV show Bounce in Dublin (plug, plug, plug). Here's some of Madeline's finer work.

The 23-year-old actor and Madeline, 22, confirmed their relationship last year at the Irish Film and Television Awards after they struck up a relationship following their flirtatious exchanges on Twitter. Because there's nothing more intimate than that.

The duo have been inseparable ever since and travelled to the US together last summer while Jack filmed with Mark Wahlberg.

Madeline said after they had returned from the US: "We had a house in LA. It was good that we were together and experiencing it together."

Meanwhile, Jack has been keen to laud praise on his missus, especially last month after she bought him the autobiography of Richard Harris for Valentine's Day.

He wrote on Twitter at the time: "Amazing Valentine's present from the best girlfriend in world."
