Lea Michele has sparked rumors that she is now engaged with boyfriend Matthew Paetz after showing off a new ring at the "Sons of Anarchy" Season 7 premiere in Los Angeles Saturday, Sept. 6, The Mirror reported.

The 28-year-old "Glee" actress, who has a guest appearance in the seventh and last season of the FX crime drama series, came seriously close to a nip slip at the event as she wore a tiny white Cushnie Et Ochs dress with a striking front cutout, according to Us Weekly.

But apart from her revealing plunging white dress, her sizeable piece of jewelry on her ring finger also grabbed the attention of some members of the press, fuelling rumors that the "Brunette Ambition" is already engaged with Paetz, whom she met on the set of her music video "On My Way."

"What an awesome night! Such an honor!@SonsofAnarchy #SOAFX," Michele tweeted after her red carpet moment at the premiere.

The Broadway veteran will play Gertie, "an empathetic truck stop waitress and single mother, who connects with Gemma during a difficult time," in Kurt Sutter's show. Filming for her supposedly one-time guest gig on the show went so well, that she may be back for more, E! News reported.

"We love her," show director Paris Barclay told E! News late last month at BAFTA's annual pre-Emmys tea party at the SLS Hotel. "We're trying to find a way to bring her back."

"Her acting was completely naturalistic," added Barclay who is also a director for "Glee."

The day after the premiere, Michele and Paetz were photographed hiking in Los Angeles - an activity that the two apparently enjoy doing together.

In between hiking with her "dating and lifestyle coach" boyfriend, Michele has also been busy filming the sixth and final season of "Glee."

"Having the best time at #Glee right now working with @chriscolfer and @janemarielynch ! GleeSeason6," she tweeted on Sept. 5.

"Sons of Anarchy" Season 7 premieres Tuesday Sept. 9 on FX with an hour-and-30-minute episode, while "Glee" Season 6 is expected to air on Fox next year.
