The newly engaged couple was spotted back in the Big Apple on Tuesday, following their romantic Bahamas vacation, where the "Sorry" singer proposed to the model at a resort.
Baldwin, 21, and Bieber, 24, both went casual for the outing. The blonde beauty opted for a white satin varsity jacket, crop top, distressed denim shorts and sneakers, while her fiance kept it cool in a striped T-shirt, Vous shorts, socks with sliders and a Bakers baseball cap.
And while all eyes were on the lovebirds, it was hard not to notice Baldwin's massive engagement ring from Bieber. The oval-shaped sparkler is set on a single band, which has become an increasingly popular look for Hollywood brides.
Notably, Blake Lively has been rocking a similar ring ever since her husband, Ryan Reynolds, proposed after they initially met while filming Green Lantern in 2010. Lively's bling is reportedly worth $2 million, and it appears she's switched out the band a few times since her and Reynolds' September 2012 nuptials.
In addition to the oval shape, plenty of celebs also seem to be loving pear-shaped diamonds as of late. Just last month, Saturday Night Live star Pete Davidson proposed to Ariana Grande with one that's worth $93,000, similar to the stunning sparklers Paris Hilton and Cardi B have been rocking from Chris Zylka and Offset, respectively.
