WATCH: Jennifer Garner gets emotional after 'Bennifer' confirmation

Her choice of photo comes after she thanked fans for joining her on a "meaningful" journey in the last year just hours after ex-husband Ben Affleck and Jennifer Lopez were snapped in a warm embrace.

Earlier this week, the actress took to Instagram to join yoga and meditation instructor, Dr Chelsea Roberts Jackson, for a 20-minute-long meditation session. At the end, Jen clearly got emotional as she came out of her meditation and praised everyone for joining them.

Jennifer looked so cute in her bridal-style dress

She said: "I don't want to mess with anyone's prayerful place, or mediation, but I want to say thank you to anyone who has meditated with us this last year because there is something about doing it together, with [Chelsea's] voice and wisdom, and the life you bring, and all these people at once, there is something so meaningful for me, and so thank you."

The mother-of-three's session came just hours after Ben Affleck and Jennifer made their romance Instagram official. The Let's Get Loud singer, 51, was seen snuggling up to 48-year-old Ben in a photo booth at Leah Remini's birthday party.

Jen and Ben - also known as Bennifer - are said to have rekindled their romance shortly after J-Lo separated from former fiancé Alex Rodriguez in April and have been inseparable ever since.
