Selma Blair's baby son is an ''adrenalin junkie''.

The 39-year-old actress says eight-month-old Arthur - her child with boyfriend Jason Bleick - is very ''sweet and outgoing'' and is already showing signs of being musical.

She said: ''[He is] sweet and outgoing. He loves music, he loves to Bang On The Drums.

''He also doesn't mind being teased, he's an Adrenaline Junkie. He likes to be thrown up in the air.''

Selma - who can next be seen in Charlie Sheen's new TV show 'Anger Management' admitted she is finding it difficult leaving Arthur for any length of time but knows it is important he is able to be ''independent'' without her.

She told People: ''I never want to leave his side. I'm one of those hovering mothers and I know it's really important to have an independent child, so I'm trying to back off, but it's hard. I love him so much, and he's so funny and cute to me.''

Despite her fame, the 'Cruel Intentions' star is happy to nurse Arthur in public and doesn't care if it upsets anyone.

She said: ''The only time he cries is if he's hungry. We all have nipples. I don't care who I offend; my baby wants to eat. If I can't get a cover over me quick enough, so be it.''
