It seems like Brian Austin Green is excited to be a father once again as he is very "supportive" of his pregnant girlfriend Sharna Burgess.

"Brian and Sharna are doing amazing ahead of Sharna giving birth. Brian is so continually supportive of Sharna and dotes on her left and right," a source told ET in an exclusive report.

"He is at her beck and call and is very gentle, supportive and understanding. It's all the qualities and some of the reasons Sharna adores him so much. They are very in love."

The “Dancing with the Stars” couple first went public with their relationship in December 2020. In February, they announced Burgess’ pregnancy through a series of sweet photos taken during their vacation in Maui, Hawaii.

"Sharna feels fantastic and nothing is more exciting to her than becoming a mom,” the source also told ET. “She already loves her baby so much and can't wait to give birth, but is also obsessed with pregnancy and finds the experience so beautiful. She's looking forward to everything about being a mom. Brian is thrilled and couldn't be more excited too."

Burgess is reportedly set to give birth in July. The baby will be Burgess’ first child and Green’s fifth son.

The “Beverly Hills 90210” alum is already a father of four: 20-year-old Kassius with ex-Vanessa Marcil and three other children with ex-wife Megan Fox: Noah, 9; Bodhi, 8 and Journey, 5.

Earlier, it was reported that Fox was "a little surprised" by the news that Green and Burgess are expecting a baby. Despite this, Fox and Burgess remain completely “cordial” and Fox is sincerely excited for Burgess.

"Megan and Sharna are completely cordial. She is happy for Sharna but she's living her own life and focused on her relationship with Machine Gun Kelly,” the source also shared.

"Brian and Megan do things for the sake of the kids and have finally gotten to a point of peacefulness and respect," another insider said. "They balance things well and Megan knows she can't block Brian from pursuing his own happiness and does like Sharna and think she's sweet."
