Justin Timberlake and Jessica Biel may have split up in March after four years together - but it seems their romance is heating up once more.
The 30-year-old Social Network star and Biel, 29, are “quietly seeing each other again”, according to US Weekly magazine.
A source told the publication: “They have been talking the whole time and decided to give it another shot.
“Jessica really wanted to get back together with him and Justin realised single life is not what it's cracked up to be.”
On Sunday, the pair are said to have visited the Black Hoof restaurant in Toronto together.
At the time of their break-up, some blamed Timberlake's 'wandering eye' connection with his Friends With Benefits co-star Mila Kunis.
He has been linked with a series of starlets since the split, including Olivia Wilde and Ashley Olsen. But he still had a soft spot for Biel, telling Vanity Fair in June: “She is the single-handedly most significant person in my life.
“In my 30 years, she is the most special person, OK? I just don't want to say much more, because I have to protect things that are dear to me - for instance, her.”
However, they are wary of jumping in too quickly and repeating their mistakes of the past.
“They're just spending time together and taking things slowly,” the source said.
