Picture perfect: Justin Timberlake and Jessica Biel pictured at the Vanity Fair party in FebruaryJustin Timberlake and Jessica Biel have have separated after more than four years together.
And MailOnline has learnt exclusively that the couple's separation comes following a very awkward birthday party.
A spokesperson for the couple confirmed the break-up, adding: 'We are confirming that they mutually have decided to part ways.’
The news comes after The A-Team actress threw an intimate surprise party for The Social Network star and made a gushing speech in front of guests that appeared to embarrass Justin.
Rumours were beginning to circulate that things were not great between the couple when the singer turned up to last month's Academy Awards with his mother, not Jessica.
Further cracks had started to show in the relationship earlier that month when Jessica threw the party for Justin at his home at the beginning of the year.

She quickly welled-up as she reminisced about the first time she met Justin and joked about how she virtually stalked him into going on a date with her.
The pair had exchanged numbers on a night out in 2007, but when Justin failed to call Jessica a few days later, she took matters into her own hands and began driving towards his house.

She joked about how she felt like a stalker, but that thankfully he did eventually call and the rest was history.
During the birthday speech, the actress gushed about how utterly head over heels in love she was with the singer-turned-actor and went on at length about how much he meant to her.
But after Jessica had finished her speech, Justin appeared dismiss her emotional speech by standing up and yelling: ‘Yeah b*tches!’
'It was really awkward,' the source told MailOnline. 'Justin's reaction was almost disrespectful. He just laughed it off.'

They added: ‘The two remain friends and continue to hold the highest level of love and respect for each other.’
The pair had temporarily split up a few months earlier in November of last year following rumours that Justin had allegedly cheated on Jessica.
Today's news is said to be Justin’s decision and sources say the actress is simply ‘devastated’.
But MSNBC are reporting that a reliable source has told them Jessica is far from devastated.
Backing Jessica up, the source has revealed: ‘Jessica is not devastated, that's just cr*p.’
They added: ‘She's a very independent, proud woman with her own career, she's fine.’
