The deejay and dancer celebrated his 40th birthday on Wednesday with the help of sons Sean Preston, 12, and Jayden James, 11. The boys gathered around as Federline blew out the “4” and “0” candles displaying his new age on a birthday cake, according to photos shared on wife Victoria Prince’s private Instagram account. Prince also shared a snap of her husband smiling as he looked down at the dessert with the caption “Happy Birthday Babe.” Federline’s birthday bash will continue this weekend in Las Vegas, where he’ll be making an appearance and perform a deejay set at the gentlemen’s club Crazy Horse III on Saturday.

This week, The Blast reported that after Federline asked for double the alleged $20,000 he collects monthly from Britney, the pop star’s father Jamie Spears — her court-appointed conservator who controls the 36-year-old singer’s finances — offered to set a budget for Federline rather than discuss increasing child support.

The singer, who divorced Federline in 2007 after nearly three years of marriage, was worth $34 million as of June 2017, per Forbes. Reps and lawyers for both Spears and Federline did not immediately return PEOPLE’s request for comment.

Time heals everything,” Federline said of coparenting with Britney in a 2015 interview with Canada’s etalk. “The family is great. It’s been a long, long journey, but I think where both of us are now, we both have somebody else we’re happy [with]. Everything just works.”
