Maggie Grace is back on the market after splitting from director Matthew Cooke, according to a report.
The Lost star first sparked rumours the pair had ended their relationship after she posted a picture on Instagram back in November (15), writing: "Recently, I've been embracing balance ... and being single again :)"
The caption accompanied a shot of a quote from the 13th Century poet Rumi, which read: "Life is a balance of holding on and letting go."
She was also seen notably minus her engagement ring as she attended the premiere of movie The Choice earlier this month (02Feb16).
And now a source has confirmed to Us Weekly that the couple are no longer engaged.
Maggie had initially announced her engagement to director Matthew on Instagram in February last year (15).
"The minute I heard my first love story, I started looking for you, not knowing how blind that was," she wrote. "Lovers do not finally meet somewhere. They are in each other all along... Matthew Cooke & I are so excited to share our engagement with you guys! I could not feel more grateful to share my life with this incredible man."
How to Make Money Selling Drugs filmmaker Matthew also posted on the photosharing site at the time, writing: "She said yes! Happiest, luckiest man in the world."
Maggie previously dated her Lost co-star Ian Somerhalder, who is now married to Nikki Reed.
She said after she split from Ian that she had decided to no longer date actors, because busy schedules keep them apart.
"I haven't dated too many actors," she told New You magazine. "I did when I was really young, for a couple of years, but it's nothing against actors. Ian Somerhalder and I are still very good friends. You can certainly reconcile schedules with actors but it takes some doing, and I just don't have that energy."
Maggie has been kept busy in recent months shooting her new movie 478, which also stars Arnold Schwarzenegger.
