Jude Meets His Lovechild
Jude, who fathered the five-month-old baby girl during a fling with model Samantha Burke, met celebrity lawyer Maurice Kutner for six hours in Miami on Thursday, ahead of the summit.
A source said: "Jude was very on edge about the meeting. The pregnancy wasn`t planned but he wants to do the right thing.
"It`s not like he can hide - as soon as Sophia can use the internet she can find out who her dad is."
Jude, who has rekindled his romance with Factory Girl star SIENNA MILLER, looked stressed arriving in Miami on Wednesday.
Asked if he was set to meet Sophia for the first time, he replied: "It`s nothing to do with you."
Samantha, 25, her mum Lea and Sophia are staying at the luxurious Mandarin Oriental - a few hundred yards from the star`s hotel.
On Saturday, Jude and Samantha - with two men thought to be her lawyers - were seen entering a local office block where their agreement is believed to have been sealed.
Samantha fell pregnant while Jude was filming Sherlock Holmes in New York over Christmas 2008.
In an interview last October she said he had yet to meet Sophia or send his well-wishes, but thought he`d "fall in love with her" once he saw her.
