Gwen Stefani and Blake Shelton are planning to “spice up” their performance at the Billboard Music Awards Sunday evening, according to Hollywood Life. The report said the couple will kiss on stage to get people talking about them.

“They have to mix up the performance since people have seen it on 'The Voice' already,” an insider told Hollywood Life. “They are planning to kiss on stage to spice things up and get people talking.”

The report comes at a time when Stefani and Shelton are rumored to have gotten engaged after the 46-year-old singer was spotted wearing a massive diamond ring recently. However, Gossip Cop debunked the rumor of their engagement.

Recently, Stefani reportedly met her estranged husband Gavin Rossdale to carry out the final formalities for their divorce. Stefani was pictured sitting in her car before leaving the place where she met Rossdale. The mother of three reportedly looked upset and emotional after her meeting. Stefani and Rossdale finalized their divorce in April, ending their 13 years of marriage.

“She seemed really upset. They were always very cool and friendly but she definitely seemed different,” a source told Entertainment Tonight. “She seemed distant and sad.”
