Miranda Lambert has a "crazy connection" with Anderson East. The 'House That Built Me' hitmaker is reportedly "serious" with her new boyfriend following her split from her husband of four years Blake Shelton. A source said: "Whenever they are together they act like two free spirits ... Miranda adores Anderson. They understand each other. Anderson has given Miranda this confidence she hasn't felt in some time. They are very supportive with each other and their careers. "Anderson and Miranda are serious. They have met both sides of their families. Both their families love what they have. They seem like they are in such a great place. They spend so much time together. They are also very involved with Miranda's animals. That's a big part of her life and Anderson is a huge animal lover." The 32-year-old singer - who made her red carpet debut with the 27-year-old musician at the Academy of Country Music Awards - wasn't worried about bumping into her former beau at the event and is happy he has found love with Gwen Stefani. An insider added to E! News: "She was not nervous at all. She is in a totally different space than [she was] months ago. She has no issues with Blake and is happy that he is in a good place in his life and also in love. "Blake and Miranda were married, so they are not strangers. Miranda will always have a certain love for Blake, but the romantic and forever feelings are gone."
