Stella – who is currently in the US on a visitor’s visa - has also visited Mel’s Malibu home for a barbeque, according to TMZ.com.
Meanwhile, Mel – who is currently locked in a bitter custody with Oksana over the custody of their 20-month-old daughter Lucia – spent yesterday (19.06.11) with the tot to celebrate Father’s Day.
The ‘Braveheart’ star – who also has six sons and one daughter with ex-wife Robyn – has recently been spending more time with Lucia after Oksana dropped her domestic violence claims against him in order to “extend an olive branch” to him.
A Domestic Violence (DV) protection order obtained against Mel - prohibiting him contacting or harassing Oksana - was also terminated as sources close to the singer say she would like to be able to communicate directly with Mel.
The couple's custody battle continues in closed court.
