Kaley Cuoco and her new boyfriend Ryan Sweeting have been dating for a short period of time and seem to be head over heels in love with each other. Now it looks like the couple may be already engaged!

The "Big Bang Theory" actress was spotted on the Los Angeles set of "The Wedding Ringer" on Tuesday wearing a ring on her left hand.

Although it was clear as day that the actress was indeed wearing an engagement ring, it is unclear whether or not the sparkler was from the tennis player or just a part of her costume for the Miramax comedy, according to the Daily Mail.

The 27-year-old wore all grey, rocking a striped top, cardigan, loose pants and nude flip-flops.

The actress took to Twitter to express her sudden happiness. "Flying high, I could literally touch the sky with you," Cuoco tweeted to her more than 1.6 million followers.

The film is set to be released next year starring Tony Award winner Josh Gad, "The Hunger Games" actor Alan Ritchson, Mimi Rogers and Kevin Hart.

The Maxim model and her 26-year-old boyfriend who she helped recover from a recent back surgery have been inseparable since early August.

Making his love for Cuoco viral, Sweeting posted a photo on his Instagram account with the caption, "A million people, all I see is her."

Us Weekly confirmed the engagement. A source told the magazine,"It's only been three months but she knows Ryan is the one."

The insider added, "When you know, you know."

The couple recently made their official public debut on the red carpet of last Sunday's Emmy Awards. The blonde bombshell wore a maroon Vera Wang gown as she stood by her man's side.

Kaley Cuoco, like her boyfriend Ryan Sweeting, was once a nationally-ranked amateur tennis player, however, she retired at age 16, the Daily Mail reported. The actress is also an active equestrian and owns four horses.
