The quirky comedian made an effort to show he still cares for his ex-wife - who he split from in December 2011 - by buying her a gold cuff for her 28th birthday last month as well as sending her a handmade meditation cushion.
A source revealed to The Sun newspaper: ''Even though they've broken up, Russell wanted to send Katy something. He thought it would be nice to let her know he's thinking of her.''
Russell's mum Barbara also remembered her former daughter-in-law's birthday, sending her special flowers and a card to her Los Angeles home.
The news of this sentimental gesture comes days after both Katy and Russell, 37, were spotted at the Los Angeles Lakers basketball season opening game on Tuesday (30.10.12) in Los Angeles, however, they were both seated at opposite ends of the VIP area and reportedly didn't speak at all.
The 'Wide Awake' hitmaker spent her birthday last week with First Lady Michelle Obama and took to twitter to share her joy at the experience, posting: ''So tonight was a great night! The PRESIDENT gave grandma and I unforgettable shout outs & now I am officially 28! Best. birthday. ever.
''NOW my bday is complete! Lunch with @MichelleObama #chicvote (sic)''
