Gwen Stefani left no stone unturned when it came to celebrating her boyfriend Blake Shelton's 40th birthday in June on social media. Now, as the songstress gears up to ring in her 47th birthday on 3 October, reports suggest that Stefani is "expecting and hoping for a ring" from the country singer. Does this mean that the power couple are ready to take their relationship to the next level?

According to a report by Hollywood Life, the country singer seems to have a few plans on his mind to celebrate the special day. "They both are going to take a few days off to spend some quality time together," a source told the gossip website, "She is definitely expecting and hoping for a ring, and can't wait to celebrate her birthday with Blake and her kids."

The news comes amid incessant rumours speculating a Christmas wedding for the music couple at Shelton's ranch in Oklahoma. In addition to this, Stefani and Shelton's adorable duet performances and PDAs have only added fuel to the wedding talks.

"Gwen and Blake are still going strong," the source continued. "He wants to marry Gwen, but has not told anyone his ideas or timing for popping the question. He is keeping that very close to his chest."

Meanwhile, the Hollaback Girl hitmaker continues to make headlines for dodging questions and giving "tongue-tied" answers on the topic of marriage. During a recent appearance on The Ellen DeGeneres Show, the mother-of-three went all smiles when DeGeneres asked her, "Before I make plans, because I make plans way ahead of time, tell me when you're getting married because I need to know. I just need to know so I can clear the schedule."

If they do get married, it would be the second time that Stefani walks down the aisle after splitting from ex-husband Gavin Rossdale last year. Shelton also has been previously married to Miranda Lambert and Kaynette Williams.
