Glee star Lea Michele has fans confused about whether she will be walking down the aisle with her co-star and real-life boyfriend, Cory Monteith.

The 25-year-old has been seen sporting a diamond ring on her nuptial finger in the past 10 days and the sparkling jewels were recently caught by a swarm of paparazzi as the star was making her way through LAX Airport in Los Angeles on Saturday.

And to further fuel rumours of an engagement, the starlet hinted on her Twitter account on Friday about "exciting" times ahead.

"Off to somewhere very exciting right now... I can't stop smiling," she tweeted.

But a day before the snaps of a smiling Michele surfaced online, Glee series creator Ryan Murphy released a clip of her character Rachel in search of a wedding dress as she prepares for her nuptials to Finn (Monteith).
