Blake Shelton and Gwen Stefani have been going strong ever since they began seeing each other. Stefani's sons adore Shelton and have grown pretty close to him. However, their camaraderie has become a source of heartache for Stefani's ex-husband Gavin Rossdale.

Rossdale is acting desperate to win back his sons and seems to be trying too hard to get their attention, reports Celeb Dirty Laundry. He is scared of getting replaced by Shelton and was recently spotted making efforts to win over his sons Apollo, Zuma and Kingston at an afternoon play date at a Los Angeles park. It looked like he was putting up a show of being a hands-on father as he played catch with the three boys.

Notably, all three sons of Stefani are said to be quite fond of Shelton who has showered them with great affection during all this time he has been with them. They are very comfortable with him becoming their second father which is driving Rossdale crazy. He is jealous of Shelton and cannot stand seeing his sons feeling content with another man.

However, other side of the story suggests that Stefani is using her children to get back at her ex-husband who cheated on her. She is said to be doing everything to eliminate Rossdale out of her life as well as her kids'. She wants to send out a clear message to him that they have moved on.

In related news, Shelton and Stefani celebrated the Thanksgiving holiday together, reports Inquisitr. The latter took to Instagram and shared a photo of herself and Shelton kissing each other. It is said that the two enjoyed the holidays in Oklahoma with their families.

Kingston and Zuma also participated in the merrymaking but the youngest Apollo was nowhere to be seen in the celebration photographs. However, it is still not confirmed if he was not present with his mother. He might have gone to Rossdale to spend time with him.

It is worth mentioning here that Stefani and Shelton split from their respective spouses last year and started dating this year after they met on the sets of 'The Voice.'
