Brangelina had come under the spotlight in recent weeks with Internet gossips speculating their relationship is in trouble.
The reports about Pitt enjoying a cosy rendezvous with ex-wife Jennifer Aniston last month added fuel to the fire.
However, Pitt insists that he is still very much in love with Jolie, and he was spotted kissing and cuddling her in front of other celebrities at the Cannes Film Festival this week.
“I am in love and I have the most beautiful family - what else can a guy want? I am the happiest man ever. We''re so lucky,” Contactmusic quoted him as saying.
The pair has six children together Maddox, seven, five-year-old Pax, Zahara, Three , two-year-old Shiloh and their seven-month-old twins Vivienne and Knox.
