But of course for those with an eye for a gorgeous gúna, the Oscar winner's relationship status came second to her stunning princess style gown which, it has to be said (and has been said) was pretty much a full-on wedding dress.
The A-line Dior Haute Couture with its full ball gown skirt, V-neckline and wrap around bodice makes for dream bridal wear, the delicate back subtle but sexy with its low crossover detail.
Jennifer continued the bride vibe with her choice of hair accessory too - a fresh flower crown (which remains a huge wedding trend, despite what Vogue has to say about it) that wrapped around the side of her hair and sat just below her pretty plaited up do.
We absolutely loved the fun, youthful look on the beaming star, so much so that we went and found some similar styles that could easily pass for the high priced Dior.
Hayley Paige, stocked in McElhinneys Bridal Rooms does several styles not unlike Jen's Dior, and we particularly love her Chandon - which is practically the double of Jen's dress - and Sloane style.
Willowby by Watters, stocked in Alice May Bridal, also do a style that could pass for the Dior - their brilliant Tilda dress, which is their first multi-way wedding gown and can be styled into several different silhouettes. See these and more of like it in our gallery below.
