is thought to be considering breast reduction
surgery before her forthcoming nuptials.
The singer-and-actress - who has previously admitted she struggled to cope with the size of her assets when she was younger - is reportedly not happy with her boobs and wants to downsize them before she gets married to NFL player Eric Johnson.
A source told In Touch Weekly magazine: "She thinks if she downsizes her breasts, she will look smaller. She's never loved having a huge chest."
The 31-year-old beauty - who was previously married to Nick Lachey
- recently explained she is working out in order to shift any extra pounds before she ties the knot.
She said: "I just have to work out on my own. There is no regimen I need to follow. There's no diet I need to follow. I just need to do some things for myself and that's it. And that will make me feel the happiest.
"I am going to dance around my bedroom and hopefully lose some weight - and lift some weights and do what I can!"
Jessica - who has also been romantically linked to 'Employee of the Month' co-star Dane Cook and Maroon 5
frontman Adam Levine
in the past - previously admitted she used to get emotional at the size of her breasts during her school years.
She added: "I was the first girl in my class to wear a bra. I remember crying in the bathtub. All my friends were super-skinny.
"I was well-endowed when I was in sixth grade. There's no way to hide them, as much as you want to bandage your boobs down."
