Hayden Panettiere's love life seems to always be in question, whether it's on the hit ABC show 'Nashville,' or in her everyday life. Now, rumors of the actress' possible engagement have surfaced again. 

When Panettiere was leaving the LAX airport on Tuesday (Aug. 13), she flashed some major bling on her ring finger as she made her way past paparazzi, according to People. But, she seemed to be hiding the sparkly diamond by holding her iPhone in her left hand. Coincidence or intentional?

While fans of the Nashville-based drama are wondering whether or not wedding bells will be chiming for Panettiere soon, she's remained mum about her possible engagement to her boyfriend, world heavyweight champion Wladimir Klitschko, with whom she's had an on-again, off-again relationship. It's been months since we last reported the engagement rumors initially, and it seems that we'll be left wondering until the news is confirmed or denied by Panettiere herself.

The couple has stepped out together in public quite a few times since rekindling their romance, which at least confirms that they're talking. And, based on the gem the actress is sporting, it appears that congratulations could be in order -- well, at least from a blurry paparazzi photo, which can be seen here.

If she is planning a wedding, Panettiere will have a busy year, as 'Nashville' was renewed for Season 2 and will air this fall.
