That agreement has been temporarily extended for February, said publicist Michael Sands, speaking on behalf of Federline's attorney Mark Vincent Kaplan.
Spears, 25, agreed last month to temporary joint custody of 1-year-old Sean Preston Federline and almost 5-month-old Jayden James Federline with visits from Federline.
Based on the terms of that agreement, Federline will continue to be allowed to visit the children at Spears' home from noon to 4 p.m. on Mondays, Wednesdays and Fridays, reports AP.
Spears filed for divorce from Federline in November after two years of marriage, citing irreconcilable differences.
Aspiring rapper Federline, 28, counter-filed, seeking spousal support and custody of the children.
