Lawrence Dallaglio believes Gavin Henson needs to decide if he wants to be a "TV personality or a rugby player" following his sacking by the Cardiff Blues.
The Wales centre was let go by the RaboDirect PRO12 club after an incident on the flight back from Scotland after last Friday's 31-3 defeat to Glasgow Warriors.
It is the latest in a string of controversies for the 30-year-old, who returned to rugby following a year-long sabbatical in which he starred in a number of reality TV shows.
Henson made his comeback at Saracens in October 2010, before a shortlived spell at Top 14 side Toulon and the ill-fated switch to Cardiff means he has played for three different clubs in the space of a year.
Dallaglio, who was speaking as an Amlin Rugby Ambassador, hailed Henson's talent but believes the versatile back needs to take some time to decide where his priorities lie.
"It's a shame for him as an individual because as a player he's shown at times immense potential," Dallaglio said. "I don't really know what happened (on the flight) so I can't comment too much about the incident, but Cardiff have decided they've had enough, which is a shame.
"Gavin now needs to go away and think about what he wants as an individual. Does he want to be a TV personality or does he want to be a rugby player? Playing rugby is really tough at the highest level and you have to be 100% focussed and dedicated to doing that to stand any chance of being successful."
Henson's reality show career has seen him star in ITV's 71 Degrees North and the BBC's Strictly Come Dancing, along with Channel 5's The Bachelor, a show in which he looked for love.
However, Dallaglio, who is no stranger to controversy himself after a tabloid scandal saw him resign as England captain in 1999, does not believe this latest incident spells the end for Henson's rugby career.
"I've met him and saw a very nice, young, affable man," Dallaglio said. "He's a real asset to any club that he plays for and to his country as well."
