Nico Rosberg has sent a tongue-in-cheek birthday message to Mercedes team-mate Lewis Hamilton on his 30th birthday.
Hamilton turned 30 on Wednesday and Rosberg, 29, took the opportunity to remind his team-mate and 2014 title rival that he is six months younger.
#HappyBirthdayLewis - 30!! Have a great party! This day is good for me. You are old now, so hopefully it will be easier for me this year :-)— Nico Rosberg (@nico_rosberg) January 7, 2015
Earlier in the day, Hamilton posted a message to his fans via Instagram.
It is hard to believe that 30 years have passed. So many great memories. I have lived my life to fullest & am grateful for the years I've had. I want to thank my beautiful mum for bringing me into this world lovingly, & my dad for being such a great father. I hope I get to see many more years & create more memories. I want to see us all help heal this world, and I hope & pray that in the not too distant future, every child gets to live a healthy & happy life just as I have. Thank you all, my fans, for supporting me. We win & we lose together. I'm going for number 3!! #godisthegreatest #bestfansintheworld #wewinandwelosetogether #partytime #showtime #love #peace #prosperity
