AceShowbiz - Hailey Baldwin and Justin Bieber will experience so many firsts that they are now a married couple. And the first of their many firsts is celebrating Hailey's first birthday on Thanksgiving after officially being Mrs. Bieber. Justin, obviously, has planned a big gift for his wifey, who will turn 22 on Thursday, November 29.

"Justin is planning on spoiling Hailey with gifts for her first birthday as his wifey, Mrs. Bieber," a source close to the 24-year-old Canadian heartthrob reveals to HollywoodLife.com. "He can't wait to spend her birthday with her and her family for Thanksgiving, before whisking her away for a romantic trip alone with just the two of them."

The insider goes on saying that the "Despacito" hitmaker "has never been more happy, in love and feeling good about life and he feels that has everything to do with Hailey." It is also said that Justin wants to make sure that Hailey knows how much she means to him through this opportunity.

For the big day, the "Love Yourself" singer is allegedly preparing "a ton of flowers" as well as "a bunch of gifts" for his wife. "[Justin] is really going all out to spoil his new bride on her birthday."

Another source reveals how the newlyweds will celebrate the Thanksgiving. "Justin didn't grow up celebrating Thanksgiving, but they are doing a dinner tomorrow night," shares the insider. Instead of a huge party, the celebration will be "a big family celebration" that includes eating cake and turkey.

And in yet another first, the model and the pop star and singer will also play host to Justin's dad Jeremy, his wife, Chelsey, at Justin's new mansion in Canada. They will also be joined by Jeremy's four kids.

"Justin and Hailey both want to be low-key as Hailey has been working a lot," the source says. "She wants to relax with Justin and enjoy the family time.

The source continues, "Justin loves spending time with his new baby sister and his other siblings, and Hailey always enjoys having the little ones around."
