The mega-watt pair came in alone, without a security detail, and managers say they shopped like any normal couple while taking pictures with anyone who asked.
Bieber, 24, commented on a photo of Baldwin, 21, on her page saying: "Dats mine". She hasn't been talking about him since they ended things again earlier this year.
"This is my ex-girlfriend, so I kinda tried to cover her face up with some shading", he said at the time.
Another source shared that Selena was shocked to learn about the engagement, nonetheless is putting her relationship with Justin "in the past". At the end of the day, she doesn't really care.
"Selena knows that Justin makes rash decisions but wishes them both the best", the second informed. Georgia was born with a rare brain disorder called Lissencephaly and Justin, Hailey and plenty of other celebs got the "G" in her honour, supposedly including Selena Gomez.
Bieber's post says he was planning to wait on an announcement but "word travels fast". Listen plain and simple, Hailey.
"My heart is COMPLETELY and FULLY YOURS and I will ALWAYS put you first!" he added. So committed to spending my life getting to know every single part of you loving you patiently and kindLY.
Baldwin and Bieber were reportedly an item before his Purpose World Tour began in 2016, and recently rekindled their romance only for the Sorry hitmaker to propose in the Bahamas last weekend and calling Hailey 'the love of my life'. I wouldn't want to spend it with anybody else.
